PDF Security

Question

I have a question about PDF security preferences. Can I change an editable pdf to readable pdf programmatically?

Answer 1

Yes - with for example PDFStamp on Windows (Command line reference)

Answer 2

My Perl CAM::PDF library has a command-line utility called rewritepdf.pl that can do this quite easily with the -P flag. The library exposes this functionality quite easily, too.

Answer 3

Yes, adding security to a PDF which stops people from being able to edit it, is quite easy using a variety of different PDF toolkits (iText, PDFSharp, Quick PDF Library, etc).
