what is a favicon

The favicon or favorite icon is essential to the brand of a website and is a finishing touch that many people tend to overlook. We’ll discuss why the favicon is so important and what it is.

What is a favicon?

The term favicon comes from two words, favorite icon. And it is a file (typically an icon) that might contain one or more small icons. When created and assigned, they complete the brand of a website. The contribute to the SEO of the website as well. They can be displayed on the top of the tab in supported browsers, in the address bar or as an icon in the bookmarks folder. When using a plugin such as ‘Speed Dial’ for Chrome and other browsers, the favicon will be displayed with the text of the page to identify your website.

History of the favicon

The first browser to support the favicon was Internet Explorer 5 in March of 1999. It was originally a file named “favicon.ico” placed in the root of website’s directory. It was used in the favorites folder for Internet Explorer and would appear next to the URL if the page was favorited. At the time it was easy to estimate who had bookmarked the website by counting the requests to the favicon.ico file. Modern browsers now load them by default and so it is not possible to check how many people have bookmarked the website by this method anymore.

File types

Originally the size of the favicon could only be 16×16 pixels and had to be 8-bit in color depth. Modern browsers now permit the use of 16×16, 32×32, 48×48 or 64×64 pixels with 8-bit, 24-bit or 32-bit color depth as favicons. Microsoft Edge, Firefox, google Chrome, Internet Explorer, Opera and Safari support ICO, PNG and non-animated GIF files as favicon, with Opera and Firefox further providing support for animated GIF, JPEG, APNG and SVG files. Safari also provides support for JPEG and SVG files.

Where is the favicon displayed?

Internet Explorer and Safari can display it in the address bar. Microsoft Edge, Firefox and Safari display the favicon in the address bar drop down. All the modern browsers (excepting Safari) display the favicon in the links bar. The bookmarks and top of the tabs for all browsers will display the favicon.

The Apple MacBook pro with touch bar version also displays the favicon inside the touch bar as a quick switchable list.

How do we display the favicon?

A favicon should follow the existing design language that your site employs. The favicon could be a simplified version of the logo for your site. Or the image of something that signifies. For example, a favicon for a banking site can be a stylized version of the dollar bill. A website on holiday planning might have a favicon with a beach umbrella. A website on cooking might use a steaming pot as a favicon. There are many methods to designing your own.


Since the size of a favicon is less, avoid as much text as possible when designing your own. In the case of Typographic style design, limiting the design to a fewer characters is advisable, for the sake of clarity.

Use of Logos
