FAQ

Can you crack a PDF password I forgot?

No — and we are honest about that. Decryption only works when you provide the correct password. We do not offer password recovery or cracking.

Is my password sent to a server?

No. Encryption and decryption run locally in your browser; the file and password never leave your device.

What encryption is used?

AES-based PDF open-password protection compatible with mainstream readers (Adobe, Chrome, Edge).
