First, let's cover the basics (experts can skip this part): A Favicon is a small image that appears in the address bar, browser tabs, and bookmarks for a website. Therefore, a good Favicon is very important for a website as it can leave a great first impression on visitors. However, the size of a Favicon is only 16×16, so creating one that clearly conveys the theme and looks attractive can be challenging. Nonetheless, there are many websites online that offer Favicon creation tools, which can help you make a Favicon you're satisfied with.
