AVIF to ICO - Free Online | FunToolX

After uploading the AVIF file, the tool converts it to ICO format. The ICO file can contain multiple size (16x16, 32x32, 48x48, 64x64, etc.), and the tool will automatically generate thumbnails of these size from the original image and package them into an ICO file. You can manually check the required size.

After AVIF decoding, it is scaled to each target size through Canvas, and then encoded into BMP or PNG frames in ICO format. All is done locally in the browser and no files are uploaded.

Mainly used for website favicon production. If your design material is in AVIF format, you can directly convert it to a browser-recognized favicon.ico file.

The online AVIF to ICO tool converts AVIF format pictures into website icon ICO format, automatically generates multiple size, and handles them locally by the browser.
