First, create a 16×16 png/ico/gif favicon and drop it in you theme’s root folder. That’s the one we will show in this example!
Add this to your theme’s functions.php.
/* Custom favicon /* ------------------------------------ */ function alx_favicon() { echo '<link rel="shortcut icon" href="'.get_template_directory_uri().'/favicon.png" />'."\n"; } add_filter( 'wp_head', 'alx_favicon' );
It’s that simple.
Useful tip: To force-refresh a favicon that you’ve updated, just add ?v=2
to the image url, like /favicon.png?v=2
.
