Frequently asked questions
- AES-256, a strong industry-standard encryption algorithm, so the password genuinely protects the file rather than just hiding it behind a viewer prompt.
- You can choose whether printing and copying content out of the PDF are allowed, on top of requiring a password to open the file at all.
- There is no way to recover it — the encryption is real, so keep the password somewhere safe before you lock the file.
- Your file is processed to produce the protected PDF and is not kept afterward, and your password is not stored — there is no account and no storage.
- No. It runs entirely in your browser and our server — no software install, no account, no email required.
