Convert PNG to ICO online, free

Need a favicon or app icon? PNG to ICO converts your transparent PNG into a Windows .ico file — the format browsers and Windows use for favicons and program icons. Your image is processed securely and never stored.

Perfect for favicons

Start from a square PNG (e.g. 256×256) with transparency for the cleanest icon. The ICO keeps your transparent background so it sits nicely on any toolbar or browser tab.
