A favicon (Favorites Icon) is the small icon that appears next to your website in browser tabs, bookmark lists, and search results. This tiny 16×16 pixel image is a vital part of your digital brand identity. A professional favicon builds trust, increases brand recognition, and helps users find your site among multiple open tabs.
1. Where Does a Favicon Appear?
| Location | Description | Size |
|---|
| Browser tab | Icon to the left of the tab title | 16×16 / 32×32 px |
| Bookmarks | Icon shown when bookmarked | 16×16 px |
| Address bar | Left of the URL (some browsers) | 16×16 px |
| Google search results | Icon next to site name | 48×48 px (min) |
| Mobile home screen | When web app is added to home screen | 180×180 / 192×192 px |
| Windows start menu | Pinned site tile | 150×150 / 310×310 px |
| PWA | App icon | 192×192 / 512×512 px |

2. Why Is It Important?
- Brand recognition: Users identify your site by color/shape among 10+ tabs
- Professionalism: Sites without favicons look "unfinished" — creates distrust
- Google search: As of 2026, favicons show in search results — click-through rate impact
- Bookmarks: Sites without favicons get lost in bookmark lists — fewer revisits
- Mobile: Home screen addition — favicon provides app-like experience
- PWA: Progressive Web App installation — favicon is required

| SVG | .svg | Modern browsers (scalable) | Optional (ideal) |
| Format | Advantage | Disadvantage |

4. Favicon Design Principles
- Simplicity: Detail gets lost at 16×16 pixels — use a symbol or letter, not full logo
- Contrast: Must be visible on light and dark backgrounds — test both
- Color: Use your brand colors — consistency and recognition
- Transparent background: PNG and SVG with transparency — clean on any surface
- Dark mode: SVG with prefers-color-scheme — visible in dark theme
- No text: Text is unreadable at 16px — prefer letter or symbol
- Test it: Check across browsers, mobile, and dark mode

@media (prefers-color-scheme: dark) {

}
</style>
<circle cx="16" cy="16" r="14"/>

| Large file size | Slow loading | Optimize — favicon max 10-20 KB |
| Blocked by robots.txt | Missing from Google results | Allow favicon path in robots.txt |
| Invisible in dark mode | Disappears on dark tabs | Use SVG + prefers-color-scheme |
