Unlock PDF — questions

Do I need the password?

Yes — this tool decrypts files you own by asking for the password you already have. It is not a password cracker, and it cannot bypass protections on other people's files.

Which encryption types can it remove?

All standard PDF encryption — RC4 (40/128 bit) and AES (128/256). The result opens without any password and keeps its content intact.

The engine downloads from a CDN — is my file uploaded?

No. Only the engine code (~1.3 MB, one-time) comes from a public CDN. The encrypted file and your password never leave your device.

What if my PDF has no password?

The tool detects it and tells you there is nothing to unlock — the original file is returned untouched in spirit, no pointless rewrite.
