Encrypt your PDF with an AES-256 password directly in your browser. Free, unlimited, and neither your document nor password is uploaded to a server.
100% private: everything runs on your computer, your files never leave your device.
Yes, free and unlimited. Encrypt as many documents as you need without an account.
No. Encryption happens in your browser, so neither the PDF nor the password you choose is ever transmitted to a server.
No signup is required. Load the PDF, set a password and download the encrypted copy.
The PDF is encrypted with AES-256, a widely trusted standard. You choose and confirm the password before the encrypted file is generated.
There is no recovery mechanism, since nothing is stored anywhere. Keep the password safe; without it the AES-256 encrypted PDF cannot be opened.
