Frequently Asked Questions
An ICO file is a Windows icon format that can contain multiple image sizes in a single file. You need ICO files for website favicons (the small icon in browser tabs), Windows desktop shortcuts, and application icons. Unlike PNG or JPG, ICO files store multiple resolutions (16x16, 32x32, 48x48, etc.) so your icon looks crisp at any size. For analyzing existing icons, use our ICO Analyzer.
ICO is a file format, while favicon refers to the website icon displayed in browser tabs and bookmarks. Favicons can be ICO files, but modern browsers also support PNG and SVG formats. For maximum compatibility across all browsers (including older versions of Internet Explorer), ICO format is recommended. Use our Favicon Generator or explore more Favicon Tools for complete favicon packages.
PNG is the best source format for ICO conversion because it supports transparency (alpha channel). For logos and icons with transparent backgrounds, always use PNG. JPG works for photos but doesn't support transparency. SVG is ideal for vector graphics as it scales perfectly to any size. HEIC (from iPhones) and WebP are also supported. Need to convert formats first? Try our PNG Converters or JPG Converters.
For website favicons, include at least 16x16, 32x32, and 48x48 pixels. For Windows application icons, add 64x64, 128x128, and 256x256 for high-DPI displays. Our converters automatically generate all common sizes in a single ICO file. Need custom sizes? Use our Icon Resizer to create the perfect dimensions.
Upload your favicon.ico file to your website's root directory, then add this code to the <head> section of your HTML: <link rel="icon" href="/favicon.ico" type="image/x-icon">. For modern browsers, you can also add PNG versions. Our Favicon Tools generate all necessary files and HTML code for complete cross-browser support.
Yes! Our ICO to PNG, ICO to JPG, and ICO to SVG converters extract images from ICO files. This is useful when you have an ICO file but need a standard image format for editing or web use. We extract all sizes embedded in the ICO file so you can choose the resolution you need.
ICO is the Windows icon format, while ICNS is the macOS icon format. If you're developing cross-platform applications, you'll need both. Our converters support both formats: use PNG to ICNS for Mac apps and PNG to ICO for Windows. Visit our Mac ICNS Tools for all macOS icon utilities.
