Favicon and touch-icon
A Favicon (“Favorite icon”, also known as shortcut icon, bookmark icon…) is usually displayed on visitors’ web browser in the URL bar or when bookmarking your website.
You can upload your own Favicon under My website / Setup / Favicon.
You can also upload a “touch icon” that will be used on iPhones or iPads when visitors add your website to their home screens (Web Clip). The uploaded image will be scaled by each device to fit their native resolution, and rounding and glass-like effects will be added automatically.
