About PNG to ICO

Browsers, Windows and many programs look for a .ico file that holds the same icon at several sizes. This converter draws your picture at each size you pick, centred on a square, and packs them into one ICO.

16, 32 and 48 px cover browser tabs, bookmarks and Windows; 256 px is used for large icons. Transparency is kept. Start from a square picture for the best fit.

Frequently asked questions

Which sizes should a favicon.ico have?

16, 32 and 48 px are enough for browsers. Add 256 px if the icon will also be used for a Windows app or shortcut.

Does it keep the transparent background?

Yes. Each size is stored as a PNG inside the ICO, with transparency.

My picture is not square. What happens?

It is scaled to fit and centred, with transparent space around it.
