Theme release 2.4 allows adding any custom font via Theme Settings -> Typography – > Custom Font. All you need is to prepare a set of font files which you can generate for free on Online Font Converter.
You can convert from pfa, pfb, pt3, sfd, ttf, otf, otb, t42, cef, cff, gsf, ttc, svg, ik, mf, dfont, bin, suit and bdf.
Online Font Converter allows uploading a source file both from your PC and from a link. You will need to check the files format which you need and press “Select the file”, then you upload the file, and download an archive.
Your next step is to upload these files to your Media Library.
