Unlock PDF: your questions answered
Can this recover an unknown PDF password?
No. It uses the correct password you provide to create an unencrypted copy. It does not guess or crack passwords.
Is the password sent anywhere?
No. Decryption runs in your browser, so both the file and the password stay on your device.
Privacy
This tool runs entirely in your browser. Your file is processed on your device and is not uploaded to a server. You do not have to take that on trust — the monitor directly beneath the tool reads your browser’s own record of every request this tab made while your file was open.
