How to remove a password from a PDF you know the password for

A password-protected PDF is a nuisance if you open it every day on your own computer. If you know the password, you can save a copy that opens without one.

This only works when you know the password. It can't crack or guess a password, and you should only unlock documents you own or have permission to change.

Step by step

  1. Open the Unlock PDF tool and choose the protected file.
  2. Enter the password you normally use to open it.
  3. Click Unlock PDF. If the password is right, a decrypted copy downloads. If not, you'll see an error and can try again.

Privacy

The work happens in your browser using a WebAssembly version of the open-source qpdf program. Your file and your password are not sent anywhere.

If it doesn't work

  • Check for typos and the caps lock key. PDF passwords are case-sensitive.
  • A very old or unusual encryption method might not be supported.
  • If you forgot the password, there is no legitimate way to recover it from the file.

Want to protect a file instead?

The Protect PDF tool does the opposite: it locks a PDF with a password using AES-256 encryption.

Frequently asked questions

Can this remove a password I forgot?

No. You need to know the password. The tool only removes protection from files you can already open.

Is it legal?

Use it only on documents you own or have permission to modify.

Is my password sent to a server?

No. It stays in your browser.
