A favicon (short for favorites icon), also known as a website icon, shortcut icon, url icon, or bookmark icon. It is an 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.
