Using Customer Fonts

Hi there
Don’t we have another way to use customer fonts then embedding them or working with svg?
At the end, I would like to validate my banners as gdn- or dcm-banner.
How are you doing this?
Thank you in advance for your help.
Best wishes, Urs

There is always the option of using broken path SVG versions imported from Sketch or XD in banners. Even simpler are PNG‘s (@2x) shrinked with optimizers.

More suggestions, anybody else?

It will bloat the file size, but what about data URIs?
