What does Unlock PDF do?
It removes password protection from a PDF you already have the password for, producing an unprotected copy.
Do I need to know the password?
Yes — this tool removes protection from a PDF you can already open; it does not crack or bypass a password you don't know.
Where is my file processed?
Locally in your browser — your PDF and its password are never sent to a server.
