What is the little logo on a website called?

The little logo displayed in a browser tab next to the page title is called a favicon. This small image helps users quickly identify a website when multiple tabs are open. Favicons are typically a simplified version of a brand’s logo or symbol, designed to remain clear even at a very small size. They enhance recognition, improve user experience, and give a polished professional appearance. Though small, a favicon reinforces identity and helps visitors keep track of the site while browsing, bookmarking, or navigating across multiple open pages.
