How to add Google fonts to TinyMCE editor in Moodle

Google has made it easy to use great looking fonts on websites, providing over 600 cross-browser fonts to date, for free. In this short post, you will learn how to add Google fonts to the default Moodle HTML editor, TinyMCE. 


  • To complete this tutorial you must be able to login to Moodle as an administrator.
  • You will also need access to the files on the server (FTP or SSH access).
  • This tutorial is for Moodle 2.3 or above (it can be done for Moodle 2.0, 2.1, 2.2 and I’m happy to extend this blog post if someone asks me for it).
  • Adding Google fonts will have a slight impact on page load time (not noticeable in most cases). The more fonts you add, the more significant the impact.
  • This tutorial also works for other Web font services such as FontSquirrelTypeKit, Adobe Edge fonts, etc.
  • Although I have never noticed any problems with this technique, don’t come and blame me if it breaks something in your Moodle installation 😉
