ICO Generator
Build a proper Windows .ico file containing several resolutions in one package. Choose the sizes you need — 16px for the address bar, 256px for large desktop icons — and download a single ICO.
Your file is processed on our server and deleted the moment your download is ready — never stored, and cleared within the hour at the very latest.

ICO Generator — frequently asked questions
16, 32 and 48 pixels cover browser tabs and Windows Explorer at standard scaling. Adding 128 and 256 handles large icon views and high-DPI displays. Including all five is a common, safe default.
