When you enable emojis, Wordpress includes code which converts the chars to the PNGs which it pulls from a CDN.

We would like to replace those with our own images.

According to formatting.php the function is here.

How do we override the emoj_url so that we are pulling the PNGs from a folder of our choosing? Can the function being replaced (ie. is it pluggable?) I tried remove_all_filters() and apply_filter() with our own function, but it doesn't work.

Looking at the code, you should be able to filter it. Something like the following should do it:

add_filter( 'emoji_url', 'wpse_232874_emoji_cdn_url' );
function wpse_232874_emoji_cdn_url( $url ) {
    return 'http://example.com/my/cdn/url/';

...replacing http://example.com/my/cdn/url/ with whatever URL you want to use.


  • That gets me most of the way there. What's weird is that the ALT tag is still replaced with the default pngs.

  • From what I can see, the alt text isn't filterable. You may be stuck there.
