Unlock PDF

Remove a PDF's opening password using the password you already know. The tool does not guess or crack an unknown password. 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

First protect this two-page sample using Protect PDF. Upload that protected result here and enter the same password. The unlocked PDF should retain both pages.

Protect the sample first

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

Enter the password, get an unlocked copy.

  1. Choose the protected PDF and enter its known password.
  2. Run Unlock PDF.
  3. Open the resulting PDF to confirm it no longer requires a password.

Try this example

Unlock a PDF using its known password result-open-63; the output PDF should open without prompting for any password.

Before you start: Only a known password is accepted; there is no attempt to guess, crack or recover a forgotten password.
