About ICO
An ICO file bundles the same icon at several sizes, such as 16, 32 and 48 pixels, so Windows or a browser can pick the sharpest one. It is still the most compatible way to ship a favicon.
ICO is only understood as an icon; editors and websites want an ordinary image. ICO holds several sizes in one file, which is what favicons and Windows shortcuts need.
