Good to know

  • You need the password: this tool doesn't crack or guess passwords.
  • PDFs that open without a password but block printing or copying can be unlocked without one.
  • Supports all common PDF encryption: RC4 (40 and 128 bit) and AES (128 and 256 bit).
  • Only remove protection from documents you're allowed to.

Your PDF stays in your browser

The file is read and changed on your device. Nothing is uploaded, so contracts, statements and IDs stay private.
