A favicon (short for "favourite icon") is a small symbol or logo that is displayed next to the name of a website in the browser tab or in the address bar. A favicon serves as the visual identity of the website and can usually consist of a small image, a logo or an abbreviation.

Favicons are an important feature in website development as they help to make a website easier to identify and distinguish, especially when multiple tabs or windows are open at the same time. A favicon can also help to increase brand awareness and recognition of a website.

Favicons are usually displayed as small square or rectangular images and are generally only a few kilobytes in size. Most modern web browsers support favicons and allow users to easily create and integrate them on a website.

A favicon can be created in various ways, e.g. by using graphic design software or online favicon generators. The favicon can then be integrated into the HTML document on the website to display it in the browser tab or in the address bar.

Overall, the favicon is an important part of website development as it can help to increase brand awareness and recognition of a website and make the website easier to navigate. A well-designed favicon can help make a website look professional and user-friendly.
