How to remove restrictions/password from a PDF

By , 2011-12-24 19:04

Adobe Acrobat PDF documents have a nice feature which allows content authors to restrict certain features or “encrypt” the document using a password. These can all be easily bypassed using the open-source Ghostscript:

gs -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=unencrypted.pdf -c .setpdfwrite -f encrypted.pdf
