The ICO (Icon) format is the standard file format for favicons — the small icons displayed in browser tabs, bookmarks, and address bars. While modern browsers support PNG favicons, the ICO format remains the most universally compatible option, especially for older browsers and Windows applications.
Unlike most image formats, an ICO file can contain multiple images at different sizes within a single file. This allows the operating system and browser to select the most appropriate size for each context. Common favicon sizes include 16x16 pixels for browser tabs, 32x32 for taskbar icons, and 48x48 for Windows desktop shortcuts.
A well-crafted favicon should look sharp at every size. The 16x16 version appears in browser tabs, the 32x32 version is used in bookmark bars and Windows taskbar, and the 48x48 version appears in Windows Explorer and desktop shortcuts. Our converter handles the resizing automatically to ensure your icon looks crisp at every dimension.
Unlike server-based converters, our tool processes everything directly in your browser using the Canvas API. Your images are never uploaded to any server, ensuring complete privacy and security. This also means instant conversion speeds with no waiting for uploads or downloads.
