Protect PDF — for your eyes only

Add a password so the PDF cannot be opened without it.

Files are processed on your device and never uploaded.

Not at the altar just yet

Protect PDF needs strong PDF encryption that runs entirely in your browser without a large download. We are building it and will not ship a version that sends your file to a server.

Frequently asked questions

When will this be available?
PDF encryption that runs fully in the browser without a large download is being evaluated. Until it meets our privacy and size bar, this tool stays disabled rather than sending your file to a server.
Will my file be uploaded when it launches?
This runs entirely in your browser — the file is never uploaded to a server.
