Linux – Removing PDF usage restrictions


I have several PDF documents which have the "no copy" and "no print" restriction bits set. Are there any free tools for removing such restrictions, on Linux?

I tried pdf2ps | ps2pdf but the size increase is horrible. The originals are fairly large too, so I'd rather use a local tool than a website.

FOSS-wise, there is PDFCrack, not sure if it does actually remove the security though, it's just a password cracker. I generally turn to some free trial software, A-PDF Restrictions Remover, it's easier to use.

It might be a lot harder if it's a recent PDF version though, I think they really increased the security recently.
