Favicon is like a signature id of your website. In this tutorial, I’m gonna tell you how to add favicon to your Joomla website.
First, open your photo editing tool like Windows Paint, Gimp or Photoshop and create a image. Then go to http://www.converticon.com or http://www.favicongenerator.com and convert your image into a favicon. These online tools will generate favicon of your image like myimage.ico. Change the name to favicon.ico and upload the favicon to the template directory, then refresh the page.
