Select your icons
Select the icons you’d like to include in your icon font from the various sets.
Generate your font and download
Once you have all of your icons added to your collection, click on the generate font button and then click on the download button.
Rename your icon files
By default, icon sets downloaded from IcoFont have the name icofont for all of their files. While you could upload these files with this name, I recommend you come up with a descriptive name for this set of icons and then rename all of your font files AND your CSS file with this new name.
Upload your icon set to Divi Upload Icons
You’re ready to upload your files! Simply drag them into the uploader on the plugin settings page and once the uploader finishes it’s job your new icons will be available to use in the Visual Builder as well as the standard backend Divi Builder.
