I have a PDF that requires a password to view. I know what the password is. I frequently open this PDF to print it, and find entering the password each time incredibly annoying. How can I remove the password from the PDF?

Since I need to print it, simply taking a screenshot isn't a good solution.

I tried printing the file to a PDF, but Preview disables the "Save as PDF..." option in the print dialog.

There's a command-line tool called qpdf that can remove the password encryption from your PDF files, even in cases where Preview won't let you save a copy of or export the PDF.

  1. Install MacPorts if you haven't already.
  2. Install qpdf on your system by typing the following in Terminal:

    sudo port install qpdf

  3. Once qpdf is installed, use it to decrypt the file by typing the following in Terminal:

    qpdf --decrypt --password=xxxxx encrypted-filename.pdf decrypted-filename.pdf

  4. Open decrypted-filename.pdf in Preview to verify that it worked!

Nathaniel's answer inspired me decide to try File/Save As... in Preview, which let me save a copy of the PDF with no password.

Save As dialog

I'm surprised that it was that straightforward, but it worked.

Doesn't work under 10.9, but then maybe it depends on the type of PDF. DavidThompson's solution worked, both Chrome and Firefox. – what Nov 1 '13 at 23:23

For those looking for a loop hole to save password protected PDF's in OS X 10.8.3 ... I found Opening the PDF in Chrome then Printing it to PDF using the Chrome dialog did the trick.

Ohhh nice you can use the "Chrome" method in FireFox as well.. – user235901 Jul 5 '13 at 9:14

You would likely need Acrobat Pro to remove it, if you can open it, are you able to print it to PDF?

Unfortunately, no. Preview grays out the "Save as PDF..." option in the Print dialog. – Brant Bobby Feb 12 '11 at 2:56

I did not find that Bobby Brant's solution worked on either 10.7.4 (the only 10.7 version I had available) or 10.8.2.

What I did find worked (most likely a loophole) was that I could export the file to TIFF (which created a massive 250MB file) and then print the tiff to PDF (which created an only slightly less awful 8MB file) --- all this from a 400kB original. Obviously the end result of this is a bitmap for each page, not a "real" pdf.
