How we handle your data

Unlock PDF

Unlock PDF by removing its opening password. Enter the password you already know; the unlocked copy is made on your device. Files stay in your browser.

Small converter download on first use.

One PDF, up to 20 MiB. The original file stays unchanged.

Use at least 12 characters. Keep a copy: there is no password recovery.

Download sample

This two-page sample is protected with the password result-open-63. Enter it and run Unlock PDF; the unlocked PDF should keep both pages.

What to expect

Protection uses AES-256 and sets a password to open the PDF; after opening, printing, copying and editing are not restricted. Unlocking requires the existing password; this tool does not guess passwords. Changing a PDF can invalidate digital signatures.

Processing stops after 30 seconds. Protected input can be up to 30 MiB; output is limited to 30 MiB.

The first run may download converter files and take a moment. If it fails, check your connection or try a smaller file. Cancel stops active processing; you can choose another file and retry.

A practical guide

Remove a password you already have.

  1. Open the password-protected PDF.
  2. Enter the password you already know.
  3. Download the unlocked copy and open it to confirm no prompt appears.

Try this example

Unlock an archived 40-page report whose password you still have, so the whole team can open it without typing the password each time.

Before you start: The tool needs the password you already know and does not guess or recover one. A wrong password stops the process and nothing is downloaded.
