PNG to ICO converter for Windows icons
Convert a PNG image into a genuine ICO image container. This icon converter is useful when an application or Windows shortcut requires an .ico file rather than a normal PNG.
Is an ICO file the same as a PNG?
No. ICO is an icon container format. Converting a PNG changes the file structure so it can be recognized by software expecting an ICO.
