Favicon
The small icon a browser shows in the tab, bookmark list and history for a website.
A favicon is the small square icon associated with a website. Modern sites ship several sizes — a 32x32 .ico for legacy support, larger PNGs for high-DPI tabs, and an apple-touch-icon for iOS home-screen shortcuts. Crawlers also use favicons in search-result snippets.
