A favicon is the tiny icon in browser tabs and bookmarks. You don't need dozens of files anymore — a small set covers everything.
The sizes that matter
- 32×32 — classic browser tab favicon.
- 180×180 — Apple touch icon (iOS home screen).
- 192×192 and 512×512 — Android / PWA.
- An SVG favicon scales to any size and supports dark mode.
Formats
Modern browsers accept PNG and SVG directly. A multi-size .ico is still a safe fallback for old browsers.
Make one
Start from a square logo, then resize it to each size above. Keep the design bold — fine detail disappears at 32px. Related: best format for logos.
