Common questions

Is my file uploaded when I use Sign PDF?

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

Does Sign PDF 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.

How large can my file be?

Up to 100 MB per file.
