A favicon (short for favorites icon), also known as a website icon, shortcut icon, url icon, or bookmark icon is a 16x16 pixel square icon associated with a particular website or webpage. A web designer can create such an icon and install it into a website (or webpage) by several means, and most graphical web browsers will then make use of it. Browsers that provide favicon support typically display a page's favicon in the browser's address bar and next to the page's name in a list of bookmarks. Browsers that support a tabbed document interface typically show a page's favicon next to the page's title on the tab. The Microsoft Windows Shell also uses favicons to represent "Internet shortcuts" to web pages.
