Smart Recommendations
Receive expert advice on creating additional icon formats to ensure optimal display across all devices and platforms.
A favicon (short for "favorite icon") is a small, iconic image that represents a website. It appears in browser tabs, bookmarks, and when users save your site to their home screen.
ICO files support multiple image sizes and color depths in a single file, making them ideal for favicons that need to display properly across different browsers and devices.
While most modern browsers now support favicons in PNG format, using the ICO format ensures the widest compatibility across all browsers and devices.
