The license permits converting to woff and woff2 if required for your projects/contracts. (You just can't "resell" those woff or woff2 files obviously.) There are many free ttf/otf -> woff/woff2 converters out there. The license is also included inside the folder where all the fonts are in the zip. I plan to massively update the entire folder/subfolder structure "soon". With separate folders for .otf and .ttf, making sure that both formats exist for every font, with an additional 20 new fonts included for free, a long .pdf list style sampling of each font for ease of searching, and improved promo images for every font (all the same size / format.) It's taking longer than expected to get this all together, but it should make browsing and using the fonts far easier for everyone. :)
