I have a couple of ebooks as PDFs with passwords, however my ebook reader (sony prs600) doesn't seem to support PDFs with passwords. What is the easiest of removing the password from a PDF (I know the password, which presumably helps a lot). It's a bit annoying buying a book and then only being able to read it in front of a computer.

With A-PDF Restrictions Remover, you can remove the password and other restrictions in a few seconds.

A-PDF Restrictions Remover is shareware ($10), try before you buy.

The trial version of this worked perfectly - I think I'll be registering ;-) – Alister Feb 17 '10 at 1:12
@Alister - if you work a lot with protected PDFs, it's well worth it :) – Molly7244 Feb 17 '10 at 12:48

You can try Easy Pdf Password Remover Free. Other alternatives are:

If none of the above worked for you, have a look at this page: 7 easy ways to unlock a PDF file.

NOTE: If you have Adobe Acrobat (not the free Acrobat Reader), you can remove the passwords from File > Document Security > Security Options by selecting No Security.

The Easy Pdf Password Remover Free only allows for passwords of 3 characters, and you can't specify a password. I couldn't get PDF Password Remover or Unlocker to work - they are both the same tool based on ghostscript or something. – Alister Dec 21 '09 at 23:03
I found that pdfunlock.com (from the 7 easy ways to unlock a PDF file) works pretty good, however it was sloooooooow. – Alister Feb 24 '10 at 7:58

PDF Unlocker worked like a charm! – Frankie Jul 10 '11 at 23:00

If you have access to a Mac (and Preview.app), you can try "File", "Print", "Save as PDF" or "File", "Save as" a PDF document.

This has removed the password on some documents for me. I don't know if these tips are applicable to Adobe Reader.
