The simplest and most complete solution for Favicon and Touch Icon on your WordPress site.
Did you know that to display your icon on the most popular devices, you need to have at least 15 different icon images (.png, .ico), one background color and a .xml config file?
Each device and browser has its own requirements for the icon image format and size. And let’s face it, your WordPress theme may have the ability to set an icon, but it’s probably just following a clean technical minimum (1 image, no background color, no .xml config) so it won’t be visible on many devices.
