What is an ICO file?

An ICO file is a specialized image format designed specifically for icons in Windows and web applications. Unlike standard image formats, a single ICO file can contain multiple versions of an image at different sizes and color depths, allowing systems to display the most appropriate version for any context. This makes ICO files essential for favicons, application icons, and anywhere consistent visual representation across different display sizes is needed.
