ICO file is a type of computer file used to store icons. Icons are small pictures representing programs, files, folders, or computer functions. ICO files contain multiple icon images in different sizes and with different color details. This allows the icon to display clearly and sharply in different contexts and sizes on your screen.
The ICO format was created by Microsoft. It was first used in Windows 1.0 in 1985. ICO files support transparency. This means that parts of the icon can be seen, so the icon can look good on a different backgrounds. ICO files typically include image sizes ranging from 16×16 pixels to 256×256 pixels, and sometimes larger.

AVIF stands for the AV1 Image File Format. It uses the AV1 video codec inside a HEIF (High Efficiency Image File Format) container. AVIF was released in February 2019. This format compresses images better than JPEG and WebP, creating smaller files without losing quality.
AVIF supports high dynamic range (HDR), wide color gamut, transparency, and animation. These features make AVIF good for photos and websites.
