Webflow only allows font upload files up to 2MB, so you might have problems uploading some fonts to Webflow.
On this pop pop studio site we use Mochiy Pop One as the font for our headings. The file has all the Japanese glyphs and was 4.6MB for the .tff file.
We don’t need the Japanese characters so we imported the Latin character set into Glyphr Studio .
Then it was a quick export as .oft and finally we converted it to .woff2 using Cloud Convert.
The final file size was 17kB, a huge saving, and easy to add to Webflow!
