What image should I upload as the source?

Upload a square image at 1024×1024 px or larger for the best results. The tool scales down to smaller sizes, and starting with a high-resolution source ensures sharp icons at every size.

Why are there so many iOS icon sizes?

iOS requires different icon sizes for different contexts: the App Store, Spotlight search, Settings, notifications, and different device resolutions (1×, 2×, 3× Retina). Xcode needs all of them to publish an app.

Can I download all icons at once?

Yes. Click "Download All" to get a ZIP file containing every generated icon named according to its pixel dimensions.
