Favicons: essential icons for websites

Favicons appear in browser tabs, bookmarks, and search results. Modern sites need multiple sizes for different devices and contexts: 16×16 for browser tabs, 180×180 for iOS, 192×192 and 512×512 for Android and PWAs. Our tool generates all these sizes automatically.
