Common questions

Is my file uploaded when I use Add Page Numbers?

No. This tool runs entirely in your browser with WebAssembly and browser APIs — the file stays on your device from start to finish.

Does Add Page Numbers work offline?

Not fully — the page and its processing engine load over the network, with the engine fetched when you first use the tool. After that, the processing itself runs entirely on your device, and a dropped connection does not interrupt work in progress.
