pdf-unlock

pdf_unlock removes security features from pdfs.

Installation

Ghostscript is required. When installing Ghostscript, make sure there is an executable called gs in your path. This should happen automatically with Linux, but Windows users will have to add the path to Ghostscript to the PATH environment variable manually, eg:

C:\Program Files\gs\gs9.21\bin

Then the Ghostscript executable gswin64.exe should be copied to a new executable called gs.exe.

Usage

Search for pdfs inside 'pdf_folder', then create new unlocked versions of the pdfs with the the suffix '-unlocked.pdf':

> python pdf_unlock.py pdf_folder

Search for pdfs inside 'pdf_folder', then unlock the pdfs and overwrite the original versions.

> python pdf_unlock.py pdf_folder -o

Search recursively for pdfs inside 'pdf_folder' and all subfolders, then unlock the pdfs and overwrite the original versions.

> python pdf_unlock.py pdf_folder -o -r
