What font/woff2 is
font/woff2 is the modern web font format — the best compression available, and the default you should serve first in an @font-face src list.
How it's used
You'll see this as a Content-Type value on requests and responses — for example Content-Type: font/woff2. It's the type associated with the .woff2 file extension. Font types identify web font formats loaded via @font-face; multipart types bundle several parts in one request body.
