The website says it runs locally. In browser JavaScript , you can import a file from local file system to JavaScript's local scope without sending it to a server. I'm guessing that's how this app works.

If you want to know for sure, open your browser's dev tools, switch to the network tab, import a file and watch to see if a network request is made.

Yes, that's exactly right. All your images are processed locally and don't leave your device. They are all processed in the web browser with javascript and your dev tools like you say should show that.

I think he means "why does it have to upload to the browser, can't it just read from the filesystem?" it should work, but browsers make it more complicated.
