Do you store my password?

No. The password is used to derive the encryption key and is never stored or logged.

What if I forget the password?

We cannot recover it. Treat strong PDF passwords like keys to a safe — back them up in a password manager.

Will all viewers ask for the password?

Yes — Adobe, Preview, Foxit, Chrome, Safari, mobile readers all support the standard PDF encryption.

Can I protect a scanned PDF?

Yes, encryption works the same regardless of content.

Can I add per-recipient passwords?

PDF supports two passwords (open + owner). For more granular control, use a DRM solution — out of scope for free PDF tools.

Password protect

pdfty's protect tool encrypts your PDF with a password using AES-256 — the standard used by banks and government. Anyone trying to open the file in Adobe, Preview, Foxit, or browsers will be prompted for the password.

Two passwords are supported: an open password (required to view) and an owner password (required to edit/print). Set one or both. Useful for sensitive contracts, financial reports, medical records, ID copies.

We never store your password — it's used to encrypt and immediately discarded. Files are deleted within 1 hour. We use pikepdf which is built on the audited QPDF library.
