About AVIF
AV1 Image File Format
An image format from the Alliance for Open Media, finalized in 2019, that stores AV1-compressed images in a HEIF container. It supports lossy and lossless compression, alpha and HDR, and its files are often smaller than WebP. Use it for web images when you want the smallest files; current Chrome, Firefox and Safari all display it.
About ICO
Windows Icon
The Windows icon format, which packs several sizes of the same image, such as 16x16 and 32x32 pixels, into one file. Each size is stored as a bitmap or a PNG. Convert to ICO to make a favicon or a Windows application icon.
