A favicon (short for "favorites icon") is a small icon associated with a website. It appears in browser tabs, bookmarks, browser history, and mobile home screens. Modern websites need multiple favicon formats and sizes to look sharp across all platforms and devices.
At minimum, you need: favicon.ico (any/multi-size for legacy), 16×16 and 32×32 PNGs for browser tabs, 180×180 for Apple Touch Icon (iOS home screen), and 192×192 + 512×512 in your web app manifest for Android and PWA. An SVG favicon is also recommended for infinite scalability.
ICO is the traditional format that can contain multiple sizes in one file — supported by all browsers including legacy ones. PNG favicons offer better quality and transparency at specific sizes. SVG favicons scale perfectly at any resolution and can adapt to dark mode using CSS media queries. A complete setup uses all three.
An Apple Touch Icon is a special icon used by iOS when a user adds your website to their home screen. It should be a 180×180px PNG image. Add it with <link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon.png">. Without it, iOS takes a screenshot of your page instead.
A Web App Manifest (site.webmanifest) is a JSON file that tells browsers about your web application. It should contain icon entries with 192×192 and 512×512 sizes for Android home screen icons and PWA install prompts. Link it with <link rel="manifest" href="/site.webmanifest">.
Common causes: (1) Browser cache — clear cache or use incognito/private mode, (2) CDN cache — purge your CDN cache, (3) Missing favicon.ico at domain root — browsers request this automatically, (4) Incorrect link tag href — verify paths are correct, (5) Multiple competing favicon declarations — check for duplicates.
The mask-icon is used by Safari for pinned tabs on macOS. It requires a single-color SVG file and a color attribute: <link rel="mask-icon" href="/safari-pinned-tab.svg" color="#2596be">. The SVG should be a simple silhouette of your logo in pure black, and Safari applies the specified color.
