The short answer

Favicon originally meant “favorites icon.” It began as a 16×16 ICO file for Internet Explorer bookmarks, but today the idea covers a family of browser and app icons.

A good favicon is not a miniature poster. It is a simplified brand cue that remains recognizable when the interface around it is busy.

Where people see it

Browser tabs and bookmarks are the familiar surfaces. Favicons can also appear in browser history, shortcuts, phone home screens, task switchers, password managers, and search results.

One source image is rarely enough for every surface. Modern packages pair scalable SVG or crisp PNG browser icons with a touch icon and web app manifest assets.

What a modern site needs

A pragmatic baseline is favicon.svg, favicon.ico, a 48×48-or-larger PNG, apple-touch-icon.png, and 192×192 plus 512×512 manifest icons. The exact set should follow the surfaces your product actually supports.
