Questions

Are my images uploaded?

No. They're converted inside this tab, and the page's security policy blocks it from sending data anywhere.

Which format should I choose?

JPG for photos you'll share anywhere, PNG for screenshots and graphics with transparency, WebP for websites. AVIF is smallest but not every app opens it yet.
