What are favicons?

Favicons are small visual elements that serve as identifiers for websites or specific webpages. Functioning as miniature representations of a website’s brand, they play a crucial role in distinguishing one online entity from another, particularly in environments where users interact with multiple tabs simultaneously within a web browser. The term “favicon” has historical roots in the “Favorites” feature of early versions of Internet Explorer, where these icons were initially used to visually mark bookmarked pages.

These tiny icons typically appear in the browser tab next to the page title, in bookmark lists, and sometimes in the browser’s address bar. As key visual identifiers for websites, they represent an important icon type for online branding. Often a simplified version of a website’s logo or a unique symbol, favicons contribute to a website’s overall branding and help users quickly locate and recognize their desired sites among a multitude of open tabs. Their consistent presence enhances user experience by providing a visual anchor for website identification.
