About this tool

What Protect PDF does

Plume's Protect PDF tool secures Portable Document Format files by applying AES-256 encryption through a password of the user's choosing. The result is a locked PDF that opens only with that password, regardless of the PDF reader or device used. The service emphasizes privacy by processing encryption locally within the browser, ensuring the file and password are never uploaded or transmitted. A strength meter assists in selecting a secure password, and the interface supports adding files via drag-and-drop, browsing, or pasting with a keyboard shortcut.
