Our most frequently used icon conversion tools
ICO is a file format used for computer icons in Microsoft Windows. ICO files contain one or more small images at multiple sizes and color depths to allow proper scaling based on display settings.
A favicon is a small icon used by web browsers for tabs and bookmarks. While ICO is the original format for favicons, modern websites often use multiple formats including PNG and SVG to provide optimal display across different devices.
For maximum compatibility, ICO format is best for Windows applications and favicons. SVG provides scalability for modern web use, while PNG offers transparency with broad support. The ideal format depends on your specific use case.
Android favicons (app icons) typically need to be in PNG format with multiple sizes from 48x48px to 192x192px. Apple favicons require specific sizes for different devices, with the main sizes being 180x180px for iPhones and 192x192px for iPads, usually in PNG format.
