WOFF2 is the compressed web font format all modern browsers require. It typically shrinks TTF/OTF files by 50–70%, which is why @font-face rules expect it.
Typical use: Convert to WOFF2 before shipping any font to a website — it is the smallest and fastest-loading option browsers support.
About the WOFF2 format
WOFF2 (W3C, 2014) is the current standard of web fonts: the same TTF/OTF outlines compressed with Brotli, typically 30% smaller than WOFF and dramatically smaller than raw fonts, plus a table-transform optimization that shrinks glyf data further. Every browser since 2016 decodes it; no modern site ships anything else.
It is strictly a web container — you cannot install a WOFF2 into the OS directly — so the workflow is one-way: desktop font (TTF/OTF) converts to WOFF2 for the site, while the source file stays for design tools. Pair it with `font-display` and subsetting for maximum loading speed.
