How to Use a PDF Viewer To Remove Password Protection From a PDF

For legal reasons, you should only ever remove password protection from a PDF that you possess and know its password. Passwords are typically added to prevent plagiarism or to encrypt the information so that it's safer to transmit online.

It's possible to follow very similar steps in most PDF viewer apps but we're using Google Chrome here as it's available on all formats including Windows, Mac, and Linux. 

  1. Open Google Chrome.

    Google Chrome new tab window
  2. Click File > Open File.

What If You've Forgotten the PDF Password?

If you've forgotten the password to one of your PDFs, it can be trickier to remove the password protection.

In most countries, the only legal use of PDF password crackers is to remove the security on a PDF file that you have permission to access. Never use a PDF password cracker or removal method for a file that isn't yours to unlock. 

There are numerous free PDF password remover tools that you can try. There's no guarantee they'll work as it depends on the security level of the PDF and other restrictions, but it's definitely worth trying.
