Download Version 13.43 (7.6 MB) - Dec. 4, 2025

ExifTool is a platform-independent Perl library plus a command-line application for reading, writing and editing meta information in a wide variety of files. ExifTool supports many different metadata formats including EXIF, GPS, IPTC, XMP, JFIF, GeoTIFF, ICC Profile, Photoshop IRB, FlashPix, AFCP and ID3, Lyrics3, as well as the maker notes of many digital cameras by Apple, Canon, Casio, DJI, FLIR, FujiFilm, GE, Google, GoPro, HP, JVC/Victor, Kodak, Leaf, Minolta/Konica-Minolta, Motorola, Nikon, Nintendo, Olympus/Epson, Panasonic/Leica, Pentax/Asahi, Phase One, Reconyx, Ricoh, Samsung, Sanyo, Sigma/Foveon and Sony.

ExifTool is also available as a Windows executable and a MacOS package: (Note that these versions contain the executable only, and do not include the HTML documentation or other files of the full distribution above.)

Windows 32-bit: exiftool-13.43_32.zip (11.1 MB)

64-bit: exiftool-13.43_64.zip (11.0 MB)

The Windows executable archives include Perl. Just download and un-zip the appropriate archive then double-click on "exiftool(-k).exe" to read the application documentation, drag-and-drop files and folders to view meta information, or rename to "exiftool.exe" for command-line use. Note that if you move the .exe to another folder, you must also move the "exiftool_files" folder to the same location.

(The Windows packages are based on work by Oliver Betz, and use his launcher. Oliver also provides self-installing versions of these executables. See this forum post if you have any problems/comments with these versions.)

MacOS Package: ExifTool-13.43.pkg (5.5 MB)

The MacOS package installs the ExifTool command-line application and libraries in /usr/local/bin. After installing, type "exiftool" in a Terminal window to run exiftool and read the application documentation.

Read the installation instructions for help installing ExifTool on Windows, MacOS and Unix systems.

A Note to Unix Power-Users

If you feel the need to use "find" or "awk" in conjunction with ExifTool, then you probably haven't discovered the full power of ExifTool. Read about the -ext, -if, -p and -tagsFromFile options in the application documentation. (This is common mistake number 3.)

What People are Saying about ExifTool

"It's the gold standard in terms of the image metadata it can access" - Darkroom Photos

"In my experience, nothing but nothing is as complete, powerful, and flexible as Phil Harvey's exiftool ... I've never seen anything that's in the same ballpark for power." - dpreview forum

"While there are a lot of image tools available, nothing comes close for accessing/updating the metadata like ExifTool" - merg's blog

"Fast, reliable and amazingly comprehensive ..." - CPAN ratings

"... the one piece of free software that gets the most detailed exif data of /any/ tool I've found." - gnome mail archives

"ExifTool makes every other EXIF reader (and writer) than I've seen, including the camera manufacturers' readers, look lame." - photo.net Nikon forum

"Insanely great tool with a long learning curve ..." - Adobe Forums

"ExifTool has been outstanding in our custom used Tesla image gallery build. We are able to aggregate image meta from our user base and incorporate this into development iterations to continually optimize our platform..." - Find My Electric

"... it's super awesome, it's super reliable and after many years of development it's still being updated!" - P_W999 blog

"ExifTool was the first and is (imho) by far the most complete, safe, well-tested, well-documented, and up-to-date software you can use to manipulate metadata" - Nine Degrees Below Photography

"... it is the mother of all EXIF utilities; the BFG of meta-data extraction; the Pan Galactic Gargle Blaster of EXIF tools ... This thing will suck the last bit of metadata out of whatever image file you throw at it!" - Open Photography Forums

"... it is total fucking gibberish to me." - Reddit Linux Questions

System Requirements

Requires Perl 5.004 or later. No other libraries or software required, but some optional Perl modules may be added to enable certain ExifTool features (for details, see the DEPENDENCIES section of the README file included in the full distribution).

Windows users: A Windows executable version of ExifTool is available which doesn't require Perl. You can also use the pure Perl version if you already have Perl installed. (You can get a good, free Perl interpreter from activeperl.com or strawberryperl.com.)

Everyone else (Mac, Unix, etc): Don't worry, you already have Perl installed.

Running ExifTool

The exiftool application provides a convenient command-line interface for the Image::ExifTool Perl package (both included in the full distribution). Once you have downloaded and extracted the distribution, you can immediately run exiftool (without building or installing) by typing "DIR/exiftool FILE" (or "perl DIR/exiftool FILE" in Windows), where DIR is the exiftool directory and FILE is the name of an image file, including directory name. Read the installation instructions or the README file included in the full distribution for help installing ExifTool.

Many command-line options are available to allow you to access a wide range of features. Run exiftool with no arguments for a complete list of available options with examples.

Running in Windows

i) From the command line:

The Perl application ("exiftool") is run by typing "perl exiftool". Alternately, you may be able to rename it to "exiftool.pl" and type "exiftool.pl", but this requires that the proper Windows associations have been made for the ".pl" extension.

The ExifTool .exe file ("exiftool(-k).exe") should be renamed to "exiftool.exe" to allow it to be run by typing "exiftool" at the command line.

If the exiftool executable ("exiftool.pl" or "exiftool.exe") is not in the current directory or your system PATH, then its directory must be specified on the command line (eg. by typing "c:\path_to_exiftool\exiftool.pl" or "c:\path_to_exiftool\exiftool").

Note that when typing commands in the "cmd.exe" shell, you should use double quotes instead of single quotes as shown in some examples.

ii) Running in the Windows GUI (not from command line):

Double-click on "exiftool(-k).exe" to read the application documentation, or drag-and-drop files and folders to run exiftool on the selected files.

Simple options may be added inside brackets in the name of the .exe file. (But note that the characters /\?*:|"<> may not be used because they are invalid in Windows file names.) In this way, the behaviour of the drag-and-drop application can be customized. For example:

Executable Name Operation
exiftool(-k).exe
Print meta information in window and pause before terminating.
exiftool(-k -a -u -g1 -w txt).exe
Generate output ".txt" files with detailed meta information.
exiftool(-k -o %d%f.xmp).exe
Generate sidecar ".xmp" files.
exiftool(-copyright='Phil Harvey').exe
Add copyright information (and don't pause before terminating).

Executable Name	Operation
exiftool(-k).exe	Print meta information in window and pause before terminating.
exiftool(-k -a -u -g1 -w txt).exe	Generate output "`.txt`" files with detailed meta information.
exiftool(-k -o %d%f.xmp).exe	Generate sidecar "`.xmp`" files.
exiftool(-copyright='Phil Harvey').exe	Add copyright information (and don't pause before terminating).

Hint: Options may also be added to the "Target" property of a Windows shortcut for the executable. Using a shortcut has 3 advantages over adding options in the file name: 1) different shortcuts may be created without requiring multiple copies of the executable, 2) characters which are invalid in file names may be used, and 3) the shortcuts can be given more meaningful (and convenient) file names.

As well, it may be useful to increase the window and buffer sizes to display more information: Right-click on the window's title bar then select "Properties" from the menu and change the window layout settings.

Verbose and HtmlDump Output

The Verbose (-v) and HtmlDump (-htmlDump) options print additional information that can be very useful for debugging or when decoding new tags.

Compare Two Files for Metadata Differences

The -diff option provides a method to show the metadata differences between two files. For example, here is a comparison of two files excluding System and Composite tags:

Tag Names Explained

A tag name is a "handle" that is used to refer to a specific piece of meta information. Tag names are entered on the command line with a leading '-', in the order you want them displayed. Valid characters in a tag name are A-Z (case is not significant), 0-9, hyphen (-) and underline (_). The tag name may be prefixed by a group name (separated by a colon) to identify a specific information type or location. A special tag name of "All" may be used to represent all tags, or all tags in a specified group. For example:

exiftool -filename -imagesize -exif:fnumber -xmp:all image.jpg

A complete list of ExifTool Tag Names accompanies this documentation. As well, current lists of available tag names and writable tag names may be obtained using the exiftool -list and -listw options. But perhaps the easiest way to determine a tag name is to use the -s option to print the tag names instead of descriptions for all information in a file. It may also be helpful to use the -G option to display the group names, and the -H or -D option to print the numerical tag ID's for reference.

Notes:

Tag names sometimes differ from their descriptions. Use the -s command-line option to see the actual tag names instead of the descriptions shown when extracting information.
When extracting information, tags will not appear in the output unless they exist in the file, even if they are specified on the command line. The -f option may be used to force all specified tags to be displayed (not including tags specified with wildcards or by -GROUP:all).
Information for a given tag name may occur in multiple locations within a single file. By default these duplicate tags are suppressed, but the -a option may be used to extract all tags.
Tag names may be suffixed by a '#' character to disable the print conversion on a per-tag basis. See the -n option in the application documentation for more information.

Shortcut Tags

Shortcut tags represent one or more other tags, and are used like any other tag when reading, writing or copying information.

ExifTool defines a few shortcut tags in the Image::ExifTool::Shortcuts module, and allows users to define their own shortcuts in a configuration file called ".ExifTool_config" in their home directory or exiftool application directory. Here is a simple example that defines two shortcuts:

%Image::ExifTool::UserDefined::Shortcuts = (
 MyShortcut => ['createdate','exposuretime','aperture'],
 MyAlias => 'FocalLengthIn35mmFormat',
);

In this example, MyShortcut is a shortcut for the CreateDate, ExposureTime and Aperture tags, and MyAlias is a shortcut for FocalLengthIn35mmFormat.

The current shortcuts may be listed with the -list option.

The ~/.ExifTool_config file may also be used to define new tags. For more information about the configuration file, see the sample configuration file included with the ExifTool distribution.

Windows tip: You may have difficulty generating a filename beginning with a '.' in the Windows GUI, but it can be done with the "rename" command at the cmd.exe prompt.

Tag Groups

ExifTool classifies tags into groups in various families. Here is a list of the group names in each family:

Either decimal or hexadecimal ID's may be used when writing. Note that unlike other group names, family 7 group names are case sensitive.)
8 (File Number)	File# (for files loaded via `-fileNUM` option)

The exiftool output can be organized based on these groups using the -g or -G option (ie. -g1 to see family 1 groups, or -g3:1 to see both family 3 and family 1 group names in the output. See the -g option in the exiftool application documentation for more details, and the GetGroup function in the ExifTool library for a description of the group families. Note that when writing, only family 0, 1, 2 and 7 group names may be used.

Writing Meta Information

When writing information, ExifTool preserves the original file by adding "_original" to the file name. Be sure to keep a copy of the original, or thoroughly validate the new file before erasing the original. (Read here for some ramblings on the subject of writing meta information.)

Syntax

Tag values are written rather than being extracted if any tag name ends with a '=' symbol (or if the -tagsFromFile or -geotag options are used). The '=' may be prefixed by '+', '-' or '<' to add a value, remove a value or set a value from file. The following table outlines the different write syntaxes:

Syntax Result

-TAG= Deletes all occurrences of TAG

-all= Deletes all meta information! ^†

-GROUP:TAG= Deletes TAG only in specified group

-GROUP:all= Deletes all information in specified group

-[GROUP:]TAG=VALUE Sets value of TAG (only in GROUP if specified)

-[GROUP:]TAG+=VALUE Adds item to a list, shifts a date/time, or increments a number

-[GROUP:]TAG-=VALUE Removes item from a list, shifts a date/time, or deletes TAG if it has the specified value

-[GROUP:]TAG<=FILE Sets tag value from contents of specified file

^† See the Writer Limitations for some limitations of this feature.

Syntax	Result
-TAG=	Deletes all occurrences of TAG
-all=	Deletes all meta information! ^†
-GROUP:TAG=	Deletes TAG only in specified group
-GROUP:all=	Deletes all information in specified group
-[GROUP:]TAG=VALUE	Sets value of TAG (only in GROUP if specified)
-[GROUP:]TAG+=VALUE	Adds item to a list, shifts a date/time, or increments a number
-[GROUP:]TAG-=VALUE	Removes item from a list, shifts a date/time, or deletes TAG if it has the specified value
-[GROUP:]TAG<=FILE	Sets tag value from contents of specified file

Quotes are required around VALUE if it contains spaces or other special characters, and around the whole argument if the '<=' syntax is used (to prevent shell redirection).

A special feature allows the print conversion to be disabled on a per-tag basis by suffixing any tag name (including 'all') with the '#' character. This has the same effect as the -n option, but for a single tag. See the -n option in the application documentation for more details.

Note: Changes to PDF files are reversible because the original metadata is never actually deleted from these files. See the PDF Tags documentation for details.

Group Priorities

ExifTool prioritizes the following types of meta information when writing:

1) EXIF, 2) IPTC, 3) XMP

Many tag names are valid for more than one of these groups. If a group name is not specified when writing information, then the information is added only to the highest priority group for which the tag name is valid (however, the information is updated in all groups where the tag already existed). The priority of the groups is given by the list above. Specifically, this means that new information is added preferentially to the EXIF group, or to the IPTC group if no corresponding EXIF tag exists, or finally to the XMP group.

Alternatively, information may be written to a specific group only, bypassing these priorities, by providing a group name for the tag. The "Writing Meta Information" section above gave the syntax rules for exiftool command-line arguments to do this. Any family 0, 1, 2 or 7 group name may be used when writing information, although not all groups are writable.

The "-tagsFromFile" Option

A special ExifTool option allows copying tags from one file to another. The command-line syntax for doing this is "-tagsFromFile SRCFILE". Any tags specified after this option on the command line are extracted from source file and written to the destination file. If no tags are specified, then all writable tags are copied. This option is very simple, yet very powerful. Depending on the formats of the source and destination files, some of tags read may not be valid in the destination file, in which case they aren't written.

This option may also be used to transfer information between different tags within a single image or between different images. See the -tagsFromFile option in the application documentation for more details.

Writer Limitations

ExifTool will not rewrite a file if it detects a significant problem with the file format.
ExifTool has been tested with a wide range of different images, but since it is not possible to test it with every known image type, there is the possibility that it will corrupt some files. Be sure to keep backups of your files.
Even though ExifTool does some validation of the information written, it is still possible to write illegal values which may cause problems when reading the images with other software. So take care to validate the information you are writing.
ExifTool is not guaranteed to remove metadata completely from a file when attempting to delete all metadata. For JPEG images, all APP segments (except Adobe APP14, which is not removed by default) and trailers are removed which effectively removes all metadata, but for other formats the results are less complete:
- JPEG - APP segments (except Adobe APP14) and trailers are removed.
- TIFF - XMP, IPTC, ICC_Profile and the ExifIFD are removed, but some EXIF may remain in IFD0. (The CommonIFD0 Shortcut tag is provided to simplify removal of common metadata tags from IFD0.)
- PNG - Only XMP, EXIF, ICC_Profile and native PNG textual data chunks are removed.
- PDF - The original metadata is never actually removed.
- PS - Only XMP and some native PostScript tags may be deleted.
- MOV/MP4 - Most top-level metadata is removed.
- RAW formats - It is not recommended to remove all metadata from RAW images because this will likely remove some proprietary information that is necessary for proper rendering of the image.

Known Problems

[2024年12月16日] HEIC images with an HDR gain map may not show the gain map image in Apple Preview after being edited by ExifTool to add new XMP. [ExifTool 13.09 fixes this by adding the new XMP with an item ID greater than existing items.]
[2024年08月01日] ExifTool for Windows supports a maximum path length of 246 characters for files. Longer path lengths give an "Error opening file" message. [ExifTool 13.07 implements the API WindowsLongPath option by default to patch this problem.]
[2023年10月02日] Panasonic PHOTOfunSTUDIO 9.5 has problems displaying some ExifTool-edited FZ1000 RW2 images, although other software (such as Adobe Lightroom, Digikam and Windows Explorer) have no problems with these.
[2020年02月18日] Hasselblad Phocus software will no longer update the small preview or thumbnail images of FFF files edited by ExifTool. This is perhaps due to some unreferenced preview information in the file that is lost when edited by ExifTool, but this does not seem to have any other effect. [ExifTool 11.88 and later issue a minor error when attempting to write FFF files, but this problem seems to be fixed in Phocus v3.5.4]
[2019年05月29日] Canon Digital Photo Professional 4 (DPP4) will destroy a CR3 image when editing if it had previously been edited by DPP4 followed by ExifTool. [ExifTool 11.45 fixes this by structuring the CR3 to make it safe for editing with DPP4, and may be used to restructure files written by older ExifTool versions.]
[2018年09月27日] The Sony Imaging Edge applications give an error when trying to open ARW or ARQ images edited by ExifTool, although other RAW image utilities including Sony IDC (Sony's older RAW image converter), Adobe Photoshop, Lightroom and DNG Converter, Apple Preview, dcraw, Capture One, Affinity Photo, and LibRaw's SonyPixelShift2DNG have no problems with these.
[2016年08月03日] Some antivirus software has been known to cause problems for the Windows version of ExifTool. Norton Antivirus may delete ExifTool when it is run, Windows Defender may slow down launching of ExifTool or hang it altogether, and Bitdefender Antivirus may block ExifTool from writing files. Presumably this is due to the way the ExifTool package for Windows works -- it unpacks executable files into a temporary directory and runs from there, which apparently may be seen as a threat by antivirus software. A work-around is to add ExifTool to the exclusion list of the antivirus software. [This shouldn't be a problem since the changes to the Windows EXE package in ExifTool 12.88]
[2016年05月27日] Adobe Camera Raw and DNG Converter 9.5.1 fail to recognize edited Samsung SRW images from some models (NX30, NX300, NX2000 and EK-GN120). [This problem was fixed for the NX models in ExifTool 10.26, and writing of EK-GN120 files was disabled in ExifTool 10.95]
In Windows, ExifTool will not process files with Unicode characters in the file name. This is due to an underlying lack of support for Unicode filenames in the Windows standard C I/O libraries. [This deficiency was addressed in ExifTool 9.79, and ExifTool now supports Windows Unicode file names with some exceptions. See the WINDOWS UNICODE FILE NAMES section of the application documentation for details.]
[2013年11月08日] Apple Spotlight and Preview (OS X 10.8.5) and Adobe Photoshop CC (version 14.0) ignore XMP in PNG images if it comes after the image data, which is where ExifTool adds new XMP. This should be considered as a bug in the Apple and Adobe software since XMP is allowed to exist after the image data according to the XMP and PNG specifications. [ExifTool 9.40 provides the PNGEarlyXMP API option to allow writing XMP before the IDAT chunk, but there are caveats associated with its use. ExifTool 11.58 and later remove this option and always write XMP before IDAT, and 11.63 and later write all text chunks before IDAT.]
[2013年04月21日] Memory available to ExifTool in the Windows EXE version is limited to a few hundred MB. This limitation has been known to cause unreasonably long processing times (almost 7 minutes) for some large EPS files (> 200 MB) which are processed much faster by the Perl version (< 6 seconds). [These memory issues are alleviated by the new Windows EXE package of ExifTool 12.88 and later.]
[2010年01月12日] There is a bug in a number of Adobe utilities which causes some edited Sony ARW images to be displayed with the wrong tone curve. This problem has been observed in Photoshop CS4 Camera Raw 5.6, DNG Converter 5.6 and Lightroom 2.6 with ARW images from the A500, A550, A700, A850 and A900. Other software such as the Sony IDC utility, Apple RAW utilities, dcraw and Capture One have no problems with edited images. [This bug is fixed in Camera Raw 6.3 and LR 3.3]
[2007年07月06日] There is a bug in the Apple RAW file support (OS X 10.4.11) which prevents some edited Pentax PEF images from being displayed properly. Other software such as the Pentax Silkypix software and dcraw have no problems with these images. [This bug is fixed in OS X 10.5.4]

Security Issues

Some ExifTool options (-config, -if, -p, -fileNUM, -api filter, -api filterw and copying arguments like "-DSTTAG<STR") have the ability to execute Perl code from external files or within command-line arguments. This may be a security problem if ExifTool is executed from another application that blindly passes untrusted file names on the command line (since they may be interpreted as ExifTool options if they begin with a dash). To be secure the calling application must either place file names after the "--" option, or ensure that input file names do not start with a dash (U+002D) or a Unicode minus sign (U+2212). One way to accomplish this is to prefix input file names with a known directory name, eg.) "./FILENAME".

On startup, ExifTool executes user-defined code from the .ExifTool_config file located in the ExifTool directory, the directory specified by the EXIFTOOL_HOME, HOME or HOMEDRIVE+HOMEPATH environment variables, or the current working directory. So care must be taken to make sure that any such file contains only trusted code.

As well, untrusted window title strings should not be used with the -progress:TITLE option.

Note that ExifTool NEVER makes an internet connection, so you can be assured that your personal data never leaves your computer.

Date/Time Shift Feature

Have you ever forgotten to set the date/time on your digital camera before taking a bunch of pictures? ExifTool has a time shift feature that makes it easy to apply a batch fix to the timestamps of the images (eg. change the "Date Picture Taken" reported by Windows Explorer). Say for example that your camera clock was reset to .&checktime(2000,01,01,':') 00:00:00 when you put in a new battery at .&checktime(2005,11,03,':') 10:48:00. Then all of the pictures you took subsequently have timestamps that are wrong by 5 years, 10 months, 2 days, 10 hours and 48 minutes. To fix this, put all of the images in the same directory ("DIR") and run exiftool:

exiftool "-DateTimeOriginal+=5:10:2 10:48:0" DIR

The example above changes only the DateTimeOriginal tag, but any writable date or time tag can be shifted, and multiple tags may be written with a single command line. Commonly, in JPEG images, the DateTimeOriginal, CreateDate and ModifyDate values must all be changed. For convenience, a Shortcut tag called AllDates has been defined to represent these three tags. So, for example, if you forgot to set your camera clock back 1 hour at the end of daylight savings time in the fall, you can fix the images with:

exiftool -AllDates-=1 DIR

See Image::ExifTool::Shift.pl (download in PDF format) for details about the syntax of the time shift string.

Note: Not all date/time information is covered by the AllDates shortcut. Specifically, the filesystem date/time tags are not included, and this command will reset FileModifyDate to the current date/time as it should when the file is modified, unless either the -P option is used, or FileModifyDate is set to something else. To shift FileModifyDate along with the other tags, add -FileModifyDate-=1 to the command above.

Renaming and/or Moving Files

By writing a new value to the FileName and/or Directory tags, files can be renamed and/or moved to different directories. This can be a very powerful tool in combination with the -d (date format) option for organizing images by date/time. For example, the following command renames all images in directory "DIR" according to the individual file's creation date in the form "YYYYmmdd_HHMMSS.ext".

exiftool "-FileName<CreateDate" -d "%Y%m%d_%H%M%S.%%e" DIR

Or a new directory can be specified by setting the value of the Directory tag. For example, the following command moves all images originally in directory "DIR" into a directory hierarchy organized by year/month/day:

exiftool "-Directory<DateTimeOriginal" -d "%Y/%m/%d" DIR

Read here for more details about this powerful feature.

Improving Performance

There is a significant overhead in loading ExifTool, so performance may be greatly improved by taking advantage of ExifTool's batch processing capabilities (the ability to process multiple files or entire directories with a single command) to reduce the number of executed commands when performing complex operations or processing multiple files.^† [One exiftool user documented a 60x speed increase by processing a large number of files with a single command instead of running exiftool separately on each file.] Also, the -execute option may be used to perform multiple independent operations with a single invocation of exiftool, and together with the -stay_open option provides a method for calling applications to avoid this startup overhead.

It has also been observed that the loading time of ExifTool for Windows increases significantly when Windows Defender is active. Disabling Windows Defender may speed things up significantly.

The processing speed of ExifTool can be improved when extracting information by reducing the amount of work that it must do. Decrease the number of extracted tags by specifying desired tags individually (-TAG) or by group (-GROUP:all), and disable the composite tags (-e) and the print conversions (-n) if these features aren't required. Note that the exclude options (-x or --TAG) are not very efficient, and may have a negative impact on performance if a large number of tags are excluded individually. The exception is XMP groups, which are bypassed in processing so they are never even extracted -- specifying --XMP-crs:all and -XMP-crd:all may speed processing significantly by avoiding processing of bulky Adobe image-editing information. The API IgnoreTags option (added in ExifTool 12.43) may also be used for significant speed benefits in some cases, especially when memory usage is significant because this may significantly reduced the required memory.

The -fast option can significantly increase speed when extracting information from JPEG images which are piped across a slow network connection. However, with this option any information in a JPEG trailer is not extracted. For more substantial speed benefits, -fast2 may be used to also avoid extracting MakerNote information if this is not required, or -fast4 if only pseudo System tags are required.

When writing, avoid copying tags (with -tagsFromFile) or using the -if or -fileOrder option because these will add the extra step of extracting tags from the file. Without these the write operation is accomplished with a single pass of each file.

^† However, note that when the -csv option is used, information from all files is buffered in memory before the CSV output is written. This may be very memory intensive and result in poor performance when reading a large number of files in a single command.

The Image::ExifTool Perl Library Module

The "exiftool" script provides a command-line interface to the Image::ExifTool Perl library module which is part of the ExifTool distribution. The Image::ExifTool module can be used in any Perl script to provide easy access to meta information. Here is an example of a very simple script that uses Image::ExifTool to print out all recognized meta information in a file:

#!/usr/bin/env perl
use Image::ExifTool ':Public';
my $file = shift or die "Please specify filename";
my $info = ImageInfo($file);
foreach (keys %$info) {
 print "$_ : $info->{$_}\n";
}

Note that some tag values may be returned as SCALAR references indicating binary data. The simple script above does not handle this case.

See the Image::ExifTool Documentation for more details.

Boldly Go where No Man has Gone Before...

There is still much unknown information in the maker notes for many camera models. (To see this information, run exiftool with the -U option.) In this area, ExifTool is very much a collaborative effort, and development relies heavily on the input from camera owners to help decode new meta information. If you manage to figure out what any of it means, send me an e-mail (exiftool@gmail.com) and I'll add your new discoveries to ExifTool. Many thanks to all who have helped so far...

Phil's Background

Phil has a master's degree in nuclear physics and is now officially retired from his position at Queen's University where he worked with the Nobel-prize-winning Sudbury Neutrino Observatory (SNO) team and other SNOLab experiments from 1990 to 2020. For SNO he wrote the software to acquire, format, store and display all of the hundreds of terabytes of data generated by the detector; software that continues to be used by SNO+ for their even greater data volume.

ExifTool started as a simple utility used to display metadata from images hosted on the SNO web site, but quickly expanded in scope as Phil got involved with digital photography beginning in 2001. During retirement Phil continues to enjoy digital photography, a hobby which he now applies to bird watching. A selection of his birding pictures may be found in his recent Birds of Kingston book.
