What sizes and formats does it generate?

It generates and lets you download the PNG sizes a modern site needs (16px–512px) plus an ICO for traditional browsers, all at once — from the small icon for a browser tab to the large icon for a phone’s home screen.

What source image gives the cleanest result?

A square, high-resolution image larger than the final output (512px or more) is ideal; enlarging a small image looks rough. Keep the design simple and avoid tiny details so it stays legible even when scaled down to 16px.

How do I add the generated favicon to my site?

Place the downloaded files on your site and add in the HTML . Putting the ICO at the root lets most browsers detect it automatically, and specifying multiple PNGs with the sizes attribute lets each device pick the right size.
