fonttools convert ttf to woff2

Question

Currenly, I'm using fonttools(https://github.com/fonttools/fonttools) to convert font file ttf to woff2 by ttx command with 2 steps

• convert ttf to ttx
• then convert ttx to woff2

But it's too slow and ttx file to big, is there any way to convert ttf to woff2 directly by using fonttools to improve performance?

Answer 1

With fonttools installed in your Python (virtualenv, pipenv, etc):

$ python
>>> from fontTools.ttLib import TTFont
>>> f = TTFont('path/to/your/file.otf')
>>> f.flavor='woff2'
>>> f.save('path/to/your/file.woff2')

NOTE: you might need to install other fontTools dependencies ('brotli', others) to allow saving with flavor=woff2 to work correctly.
