Password Protect PDF
Add a real password to a PDF, or remove one you already know — genuine AES-256 encryption, processed entirely in your browser using an open-source library. Nothing is uploaded, and there's no way to recover a forgotten password since it's never sent anywhere.

Processed entirely on your device — this file is never uploaded anywhere.
You don't have to take this on faith:
- Open your browser's developer tools (F12, or right-click → Inspect) and click the Network tab.
- Select a file and use this tool as normal.
- Watch the Network tab — no request fires when you select, process, or download. If your file were being sent anywhere, it would show up there.
