PNG, JPG, WebP supported — square images work best
Need to convert any image to a multi-size ico favicon file — choose your sizes and download instantly quickly? Image to ICO handles it right in your browser with no uploads, no accounts, and no watermarks. It supports common image formats like JPEG, PNG, and WebP, and delivers results instantly using client-side processing. Your files stay on your device at all times.
The ICO format is a container that stores multiple image sizes in a single file. Browsers load the most appropriate size depending on context: 16×16 for browser tabs, 32×32 for taskbar pinning, 48×48 for desktop shortcuts, and 128×128+ for high-DPI displays. A proper favicon.ico bundles all these sizes so browsers can choose the best fit automatically.
For broad compatibility, include at minimum: 16×16 (browser tab), 32×32 (Windows taskbar / Safari tab), and 48×48 (Windows site icon). For better HiDPI support add 64×64 and 128×128. Some modern setups also use 256×256 for ultra-HiDPI displays. Including all sizes is safe — browsers simply pick the most appropriate one.
Yes — modern browsers (Chrome, Firefox, Edge 80+) support SVG favicons via <link rel="icon" type="image/svg+xml" href="/favicon.svg">. SVG favicons are resolution-independent and support dark/light mode adaptation using prefers-color-scheme inside the SVG. However, ICO files remain the safest fallback for older browsers, iOS Safari, and Windows shortcuts — so providing both is the recommended approach.
