What is a .ICO File?
A .ICO file is an image file format primarily used in Microsoft Windows for icons. These icons serve as visual representations for applications, documents, and folders. What makes .ICO files unique is their ability to store multiple images of varying sizes and color depths within a single file. This allows the operating system to select the most appropriate icon for different display resolutions and scaling factors. Operating systems often use standard size sets to adapt icon displays to various application environments; for example, both .ico (Win) and .icns (Mac) files contain multiple sizes.
