ICO Converter
Windows shortcuts, desktop apps and some websites still expect an .ico file. This converter packs your image into one .ico containing the icon sizes you select, from 16 up to 256 pixels.

Frequently Asked Questions
What is the difference between an ICO and a favicon?
A favicon is just how an icon is used on a website. The .ico file is one format for it. The Favicon Generator also produces PNG sizes and HTML tags, while this tool focuses on a single custom .ico.
Which sizes should I include?
For websites, 16, 32 and 48. For Windows program or shortcut icons, also include 256.
