Fonts and bonus files
Our fonts always come as OTF and/or TTF files. These are installable font files. We have written a tutorial in which we explain what these formats are and the differences between them.
Simply put, OFT is a modernized version of TTF. However, in most instances either format will work great. We usually recommend our customers to use the OTF version as it has some more advanced features.
If you're looking for fonts in a Webfont format, please see our Webfont help article.
Some fonts can also come with bonus files. You can often see which file format these come in by looking at the product page or in the preview images.
