Password-protect a PDF — free, no sign-up

Add a password and AES-256 encryption to a PDF so only people with the password can open it.

Password-protect a PDF

Upload a PDF and set a password — download an encrypted copy.

Anyone opening the PDF will need this password. We don't store it.

Upload a PDF, choose a password, and download an encrypted copy that requires that password to open. Strong AES-256 encryption, no watermarks, no account. We use your password to encrypt the file and then discard it — it's never saved.

Frequently asked questions

How strong is the encryption?+

AES-256 (PDF 2.0 / revision 6) — the modern standard supported by Acrobat, Preview, and every current PDF reader.

Do you store my password?+

No. It's used to encrypt the file during the run and then scrubbed — we don't keep it, and it's never written to our database or logs.

What if I lose the password?+

The file can't be opened without it and we can't recover it — that's the point of encryption. Keep it somewhere safe.

Do you keep my file?+

No — files uploaded through the free tool are deleted automatically a few hours after the run.

Need this at scale?

Chain this into a full pipeline — extract, transform, route, deliver — and run hundreds at once.
