What is a Favicon?
A favicon (short for "favorite icon") is a small, 16x16 or 32x32 pixel icon associated with a particular website or webpage. Favicons appear in browser tabs, bookmarks, history, and other places to help users quickly identify and recognize your website. Modern websites use multiple favicon sizes and formats to support different devices and use cases, including Progressive Web Apps (PWAs).
