A favicon is an icon which can be associated with a webpage and is displayed in a browser tab (together with the page title) or in the address bar. The favicon is usually similar to the website's logo, and it allows users to visually identify the websites they have open in the various browser tabs. The icon's dimensions should be 16x16 pixels or 32x32 pixels, using either 8-bit or 24-bit colors. The image's format can be either PNG, GIF, or ICO.
