How to remove pdf password

Unlocking removes password protection from a PDF you can already open, producing a copy that opens without a prompt. It requires the correct password — it is not a password recovery tool.

  1. 1

    Choose your PDF

    Drop the protected document.

  2. 2

    Enter the password

    Type the password that currently opens the file.

  3. 3

    Download

    Click Unlock and the unprotected PDF downloads.

Your files never leave your device

Unlike most online PDF tools, this one uploads nothing. Everything runs inside your browser, so your document is never transmitted, never stored on a server, and never seen by anyone but you. Once the page has loaded you can disconnect from the internet entirely and the tool still works.

Frequently asked questions

Can this crack a password I do not know?
No. You must supply the correct password. This tool removes protection from documents you are already able to open — it does not break or guess passwords.
Is my password sent anywhere?
No. The document is decrypted on your own device. The password and the file both stay in your browser.
Why does it say the password is incorrect?
PDFs can carry both a user password (to open) and an owner password (to change permissions). Make sure you are entering the one that opens the document.
Is removing protection legal?
Only remove protection from documents you own or are authorised to modify. Whether a given use is permitted is your responsibility.
