What actually changes
TTF and WOFF are not the same picture in two wrappers.
The font is wrapped in the WOFF container with zlib compression, typically producing a file around 40 percent smaller than the TTF.
Worth knowing first
WOFF is a compatibility target now, not a default. Every browser released in the last decade supports WOFF2, which is meaningfully smaller, so shipping WOFF as the primary format costs bandwidth on almost every visit.
Questions
TTF to WOFF, answered
Which browsers need WOFF?
Internet Explorer 11 and a handful of very old mobile browsers. Nothing current.
Can I serve both?
Yes, listing WOFF2 first in the src descriptor. Browsers take the first format they understand.
