Batch export all open windows in Gimp

Question

I just manually edited 200+ .PDF files in gimp and I would like to batch export all of them at once (in .PDF) instead of exporting one by one.

I have the plugin-registry installed, but I'm not sure if I can take advantage of it in this case.

I think what I need is a script / console command, but I know nothing about Python.

Thanks for your help.

• BogdanM: I am having the same issue. I need to open a bunch of files, then export all of them.
• RokeJulianLockhart: This question is similar to: Save as on multiple files at once (GIMP). If you believe it’s different, please edit the question, make it clear how it’s different and/or how the answers on that question are not helpful for your problem.
• RokeJulianLockhart: gitlab.gnome.org/GNOME/gimp/-/issues/11368 suggests this.

Answer 1

I'm having the same problem. My solution was:

1. copy images to subdirectory
2. open all copied images and edit them how you want.
3. use the saveALL.scm script provided below (i can't remember where i found it). this script will overwrite opened files, but will save your edits on all opened images.

4. if you're like me and you want to the edited output file to be a different format, follow up with ImageMagic and convert all files in the subdirectory using the mogrify function.

• AntumDeluge: Thank you so much! This worked for me on MacOS 10.10.5 with GIMP 2.8.22.

Answer 2

According to @bishopia, the following script implements exporting all layers instead of only active one.

(define (script-fu-save-all-images)
 (let* ((i (car (gimp-image-list))) 
 (image) 
 (merged-layer))
 (while (> i 0)
 (set! image (vector-ref (cadr (gimp-image-list)) (- i 1)))
 (set! merged-layer (car (gimp-image-merge-visible-layers image CLIP-TO-BOTTOM-LAYER)))
 (gimp-file-save RUN-NONINTERACTIVE 
 image 
 merged-layer 
 (car (gimp-image-get-filename image)) 
 (car (gimp-image-get-filename image)))
 (gimp-image-clean-all image)
 (set! i (- i 1)))))
(script-fu-register "script-fu-save-all-images" 
 "<Image>/File/Save/Save and Overwrite ALL" 
 "Save and Overwrite all opened images (CLIP-TO-BOTTOM-LAYER)" 
 "Saul Goode" 
 "Saul Goode" 
 "11/21/2006" 
 "" 
 )
