What font/ttf is
font/ttf is a raw TrueType font. It works on the web but is larger than WOFF2, so it's usually a last-resort fallback.
How it's used
You'll see this as a Content-Type value on requests and responses — for example Content-Type: font/ttf. It's the type associated with the .ttf file extension. Font types identify web font formats loaded via @font-face; multipart types bundle several parts in one request body.
