Why Your PDF Tool Shouldn't Need Your Files

Privacy matters when your documents are sensitive.

Most online PDF tools upload your file to a remote server, process it, then return the result. Even if it’s deleted later, your document left your device.

RadiantPDF runs directly in your browser. Files move from your disk into browser memory, get processed, then return to your disk — no server involved.

When this matters most

Local‑first by design. No uploads, no server storage.
