How to Unlock a PDF — Remove Password Protection Free | PDF AI Work Blog

PDF AI Work Team·July 30, 2026

Forgot the password to your PDF? Or received a protected file you need to edit? The Unlock PDF tool removes password restrictions from PDFs you have the password for.

Important: You Must Know the Password

This tool removes protection from PDFs you own or have legitimate access to. You need to provide the correct password to unlock the file — this is not a password cracker. It's for removing restrictions when you know the password but want to permanently unprotect the document.

  1. Open Unlock PDF
  2. Upload your protected PDF
  3. Enter the password
  4. Download the unrestricted PDF

To add protection: Protect PDF. For other document modifications: Edit PDF.

Free, no signup. Unlock your PDF now.
