Unlock PDF (Known Password)

Remove the password from a PDF you already know the password for, in your browser. It cannot recover or bypass a forgotten password.

🔒

Your PDF and password are processed locally in your browser. They are never uploaded to JoeLucky, stored, or logged.

Only for PDFs whose password you already know. This tool cannot recover, guess or bypass a forgotten password.

Unlocking produces a new PDF that opens without a password; your original file is not changed.

WHAT IS UNLOCK PDF (KNOWN PASSWORD)?

Unlock PDF removes the password protection from a PDF when you already know the password, and gives you a new copy that opens without one. Everything happens in your browser.

Important

  1. For files whose password you know. This tool cannot recover, guess or bypass a forgotten password.
  2. A wrong password is reported clearly; an unencrypted file is told it needs no unlocking; an unsupported encryption format is explained.
  3. Handles AES-256, AES-128 and the older RC4 formats (for opening old files whose password you know).

How to use?

  1. Upload the password-protected PDF.
  2. Enter the password you know.
  3. Click "Unlock & Download" to get the copy that needs no password.

Frequently asked questions

Can it crack a password I have forgotten?

No. It only removes the protection when you already know the password and enter it. It never guesses, brute-forces, uses dictionaries or bypasses a password in any way — a wrong password simply returns "incorrect password".

Which encryption formats are supported?

The standard password security handler with AES-256, AES-128, and the older RC4-128 and RC4-40. Unsupported formats (for example certificate / public-key encryption) get a clear "not supported" message rather than being mistaken for unencrypted or corrupt files.

Are my file and password uploaded?

No. Everything runs in your browser; neither the file nor the password is sent to JoeLucky, and the password is never stored or logged. You download a new PDF that opens without a password, and your original file is not changed.
