PDF Boost AI
OpenOn-device

Unlock a password-protected PDF

Enter the password you already have, then download an open copy. PDF Boost AI cannot guess or break passwords — it only uses the one you type.

  1. 01

    Drop the locked PDF.

  2. 02

    Enter the user password.

  3. 03

    Download the unlocked copy. Pages are redrawn into a new, open file.

What “unlock” means here

If you know the password, pdf.js can open the file in this tab. PDF Boost AI then writes a new PDF without the encryption dictionary.

This is not a cracking tool. Wrong password, no file. That is intentional.

Questions

Will this work on owner-password-only files?
If the file opens without a user password in your reader, you may not need this tool. If Chrome prompts you, type that password here.
