You can always see which file formats the products come in on the individual product pages. Beneath the images, you will see a short product description in which the available file formats are listed.
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 are and what the difference is between them.
OFT is, in fact, the upgraded and improved version of TTF. In most applications, both font types work great. We usually recommend our customers to use the OTF version as it gives you more possibilities.
Some of the 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.
