Font convert

POST /api/font-convert

Decompress a WOFF2 font into TTF/OTF. Useful when you have a WOFF2 file but need the original sfnt for tooling that does not understand the WOFF2 wrapper.

Decompresses a WOFF2 font and returns the original sfnt (TTF or OTF) bytes. Useful when you have a WOFF2 file but need an sfnt — most font tooling, foundries, OS-level installers, and older browsers expect TTF/OTF. The conversion is exact: the output is the same bytes the WOFF2 encoder originally compressed, so glyph metrics, kerning, and OpenType features all survive verbatim.
