### Combine PDF files
104+
105+
Combines all the PDFs in the current working directory into
106+
a single PDF. The program also prompts user if they want to include the cover page of all the PDFs that are being merged.
107+
108+
It is recommended to rename files so that they are lexographically in the same order as they are to be combined and put them in the same directory as the script.
109+
The combined PDF would be saved as the name of the first file in the lexographic order prepended with 'combined'.
110+
111+
__Ensure that none of the PDFs are encrypted.__
112+
113+
#### Usage:
114+
115+
```py3
116+
python3 combinePDF.py
117+
```
118+
119+
Choose whether you want to include the cover page of each individual PDF by entering `y` or `n`.
120+
121+
### Add Watermark to PDF
122+
123+
Add watermark to every page of a PDF document.
124+
125+
The watermark file should be a PDF too. If you want to make an image or text as a watermark, put them in a word file and stylize as per you want it to appear as the watermark and then export the file as PDF. This file would be the watermark file.
126+
127+
__Ensure that none of the PDFs are encrypted.__
128+
129+
#### Usage:
130+
131+
```py3
132+
python3 addWatermarkPDF.py
133+
```
134+
135+
Enter the filenames of the PDF to be watermarked and then of the watermark PDF.
136+
137+
### Encrypt or Decrypt a PDF
138+
139+
Encrypt an unencrypted PDF file with a password or decrypt a password-protected PDF and save as an unencrypted file.
140+
141+
#### Usage:
142+
143+
```py3
144+
python3 encryptDecryptPDF.py
145+
```
146+
147+
Choose whether you want to encrypt or decrypt a PDF and then enter the name of the file. You would be prompted to enter the password either to encrypt the PDF or decrypt it, as selected earlier.
