Have you ever wondered how some sites add those little custom graphics to the address bar, at the top of the browser? For example, Google adds the letter G, and Adobe adds its logo. You too can add any image to your site – you just have to get it in the right format.
Fortunately, turning a graphic into a favicon (or shortcut icon) is easy and free with Favicon from Pics (www.htmlkit.com/services/favicon). Just upload any graphic of your own, and this online tools automatically converts it into a favicon that you can use on your site. After your image is saved in the ICO format, you simply upload it to the main root folder of your Web site, and your image is automatically displayed on the address bar in a browser.
Favicons also appear in the list of bookmarks, or favorites (which is where the name comes from) when a visitor saves your Web sites in a browser. Thus, including a favicon can make your site stand out from a list of saved Web addresses and can help build and strengten your brand.
