Favicon
A small icon displayed in browser tabs and bookmarks to identify a website.
Definition
A favicon (favorite icon) is a small icon associated with a website, displayed in browser tabs, bookmarks, and history. Originally 16x16 pixels, modern favicons come in multiple sizes for various contexts including mobile home screens and Windows tiles.
Proper favicon implementation includes multiple formats and sizes, with SVG favicons gaining support for sharp rendering at any size.
Why It Matters
Favicons help users identify websites among many open tabs and bookmarks. They're a small but important brand touchpoint that contributes to professional appearance.
Missing or broken favicons look unprofessional and make sites harder to identify in crowded browser tabs.
Examples in Practice
A favicon set including 16x16, 32x32, 180x180 (Apple touch), and 192x192 (Android) sizes.
SVG favicons that scale perfectly and can even adapt to dark mode preferences.
Brand-consistent favicons that match the website's primary logo or icon.
