Why convert AVIF to ICO?
AVIF is a next-generation format based on the AV1 video codec, offering the smallest files of any common format at a given quality, with transparency and HDR support. ICO is the Windows icon container, used for application icons and website favicons. It can hold one or more small images, typically 16x16 up to 256x256 pixels.
- Move to a lossless ICO file so no further quality is lost in editing — though detail already lost in the original AVIF cannot be restored.
- Generate a Windows favicon or app icon — ICO is the format browsers and Windows expect for icons.

Converting to ICO stops any further quality loss, but it cannot recover detail already removed by the original AVIF compression. The result matches your source as closely as possible.
Does ICO support transparency?
Yes, ICO supports a transparency (alpha) channel, so transparent areas are preserved.
What is the largest file I can convert?
You can convert AVIF images up to 5 MB. Because processing is done on your device, very large images depend on your device's available memory.
