Unlock PDF - Remove a PDF Password You Know, Free

Upload the password-protected PDF, enter the password you normally type to open it, and click Unlock PDF. The tool decrypts the file and gives you a copy that opens instantly with no password prompt. The original stays untouched on your device, so you can keep a protected version too.

No, and that is deliberate. This tool removes encryption using the correct password you supply — it never cracks, guesses, or bypasses passwords. If the password you enter is wrong, decryption fails and you will see a wrong-password error. For a PDF whose password is truly lost, contact whoever created the document.

Yes, completely free — no signup, no watermark, and no file limit beyond the standard upload size. Upload the PDF, enter its password, and download the decrypted copy without paying anything.

Your PDF and password travel over an encrypted HTTPS connection, the file is decrypted on our secure servers, and both the upload and the unlocked result are automatically deleted. The password is used only to decrypt your file during processing and is never stored.

The tool removes the open (user) password — the one a reader must type before the document displays — including PDFs protected with AES encryption. As long as you can open the file with the password you have, the unlocked copy will open freely and print, copy, and edit normally in any PDF reader.

Yes. Our PDF Password tool does both directions: it can encrypt a PDF with a new AES-128 password or remove one you know. Use it whenever you want to re-protect the unlocked file before sharing it.
