Converting an encrypted .ps file to a .pdf file

  • 772

I want to convert my .ps file (which was created from an encrypted .pdf file) back to a .pdf format.

Using ps2pdf in ghostscript gives me the following message on my command prompt:

This PostScript file was created from an encrypted PDF file.
Redistilling encrypted PDF is not permitted.

Is there anyway to convert my .ps file back to .pdf if I know the password of the original encrypted .pdf file from which the .ps file was created?

  1. You can open the .ps file in a text editor of your choice, find the line Removing the following eleven lines is illegal, subject to the Digital Copyright Act of 1998. and remove the following eleven lines, starting with mark currentfile eexec and ending with cleartomark, save and run ps2pdf.

  2. Why don't you use imagemagick? Try this:

    convert myfile.ps myfile.pdf

    Hope it helps you
