How to Create an Effective Favicon Set for Modern Browsers
A proper favicon implementation requires multiple file formats and sizes to support browser tabs, bookmarks, app icons, and PWA manifests. This guide covers the minimal set of files every website needs.
Key Takeaways
- The classic 16x16 favicon.ico is no longer sufficient.
- Add these four link tags to your `<head>`:
- SVG favicons are resolution-independent, making them crisp on any screen density.
- The manifest.webmanifest file declares your PWA icons.
- Serving only favicon.ico without other sizes.

Beyond favicon.ico
The classic 16x16 favicon.ico is no longer sufficient. Modern browsers and operating systems use icons in various contexts that require different sizes and formats.
The Essential Favicon Set
| File | Size | Purpose |
|---|---|---|
| favicon.ico | 32x32 | Browser tabs, bookmarks, legacy |
| icon.svg | Scalable | Modern browsers (dark mode support) |
| apple-touch-icon.png | 180x180 | iOS home screen |
| icon-192.png | 192x192 | Android Chrome, PWA |
| icon-512.png | 512x512 | PWA splash screen |
| icon-mask.png | 512x512 | Android adaptive icons |

SVG Favicon Benefits
SVG favicons are resolution-independent, making them crisp on any screen density. They also support CSS, including prefers-color-scheme for automatic dark mode adaptation.
Web App Manifest
The manifest.webmanifest file declares your PWA icons. Include at least 192x192 and 512x512 sizes, plus a maskable icon for adaptive icon support on Android.
Common Mistakes
- Serving only favicon.ico without other sizes.
- Using
sizes="any"on the .ico link (usesizes="32x32"instead). - Forgetting apple-touch-icon (iOS defaults to a screenshot).
- Not testing maskable icons in Android's safe zone.
