Password-protect a PDF
Open a PDF, type a password, and get an encrypted copy (AES-256). The password never leaves your browser, and the file is never uploaded.
How it works
- Open the PDF you want to protect.
- Enter a password — the file is encrypted with AES-256.
- Save the protected PDF; this password will be required to open it.
Frequently asked questions
What encryption is used?
Modern AES-256 encryption. The password is handled in your browser and is never sent anywhere.
What if I forget the password?
The password can't be recovered — neither the site nor we store it. Remember it or keep it somewhere safe.
