Private by design — no upload

Most free online tools do this by uploading your file to their servers. This one doesn’t: it runs entirely in your browser, and the page ships with a strict security policy that blocks every outbound network request, so your file physically cannot leave your device. No account, no email, no upload, no watermark.

Formats and positions

Choose a numbering style — “1, 2, 3”, “1 of N”, “Page 1”, or “Page 1 of N” — and a position (bottom-centre, the corners, or top). Set the starting number and font size. Numbers are stamped onto each page while your existing content stays untouched.

Good to know

No watermarks, no limits, and it runs offline after the page loads.
