Is my file uploaded anywhere?
No. poqpoq is a static site — the page you're looking at is a bunch of JavaScript your browser downloaded once. It runs entirely on your device. There is no upload endpoint. When you open your browser's Network tab during a conversion, you'll see zero requests going out.
