Free AVIF to ICO converter online
Need a ICO instead of a AVIF? This free converter turns AVIF files into ICO images right in your browser. Add as many files as you like, adjust the settings and download the results individually or together as a ZIP.
AVIF is the newest mainstream image format, based on the AV1 video codec. It often beats WebP by another 20 percent in file size and supports HDR and transparency. Support outside of modern browsers is still patchy, so AVIF files frequently need converting before they can be edited, printed or uploaded.
ICO is the Windows icon format and the classic format for website favicons. A single .ico file can hold several sizes (16x16, 32x32, 48x48 up to 256x256) so the operating system or browser can pick the sharpest one.
