What is a favicon.ico?
A favicon.ico, also known as a favicon, is a small image file that represents a website, much like a logo. The most important thing to remember is that it will be displayed alongside your website’s name in a user’s favorites menu (this includes “bookmarks” in other browsers). It is also usually displayed in the tab title (if the browser supports tabs) while surfing your site. In some browsers, it is displayed in the URL or location bar, too.
