For a website favicon, the standard recommendation is to include 16×16, 32×32, and 256×256. Modern browsers use 32×32 for tab icons, 16×16 for bookmarks, and 256×256 for high-DPI displays. Windows uses 48×48 for desktop shortcuts.
For a complete cross-platform app icon, include all sizes: 16, 32, 48, 64, 128, and 256. Our converter bundles all selected sizes into a single .ico file.
After downloading your .ico file, upload it to your website's root directory and add this to your HTML head: <link rel="icon" href="/favicon.ico">
