Is Protect PDF really free and private?

Yes. Protect PDF on hamarapdf is free forever with no login or signup, and it runs entirely inside your browser. Your files are processed on your own device and are never uploaded to any server.

Do my files get uploaded when I use Protect PDF?

No. Unlike cloud tools, Protect PDF does all processing locally in your browser using WebAssembly. You can open your browser's Network tab and confirm that nothing is transmitted — ideal for financial statements, hr records, intellectual property.

Open the tool, drop your file into the workspace, adjust any options, and download the result. Everything happens on-device, so it also works offline once the page has loaded.

Can I use Protect PDF for sensitive business documents?

Yes — because files never leave your device, Protect PDF is well suited to financial statements, hr records, intellectual property. For fully offline use, the hamarapdf desktop app packages every tool to run without any internet connection.

Security

Password protect

Encrypt a PDF with a password. Unlike the rest of hamarapdf, password protect is handled on your own ModelCam server, because real PDF encryption cannot be done safely inside a browser. The tool says so before you choose a file. Runs on your ModelCam server (qpdf) — the only tool that leaves your device, because real encryption must.
