If this is implemented fully in the browser, the file wouldn’t actually be uploaded anywhere. Modern browsers can read local files via the File API and process them with JS/WebAssembly.

One way to verify is to open the Network tab in DevTools and see if any requests are made when editing the PDF.

I totally understand the concern.

That’s exactly why I suggest installing it as a PWA and then disabling network access on the PWA. In my opinion, that’s actually the best way to use it.
