Questions

Do my files get uploaded?

Yes — this one runs on a server, so the file is sent over the network and processed there. If you would rather nothing left your device, use the browser tools on the main page instead.

Is there a watermark or a sign-up?

Neither. No account, no watermark on the output. The practical limit is your device memory — large scanned files use more of it.
