WOFF2 is the standard web font format: it packs the same glyph data of a TTF with Brotli, averaging about 30% smaller than WOFF and far smaller than the raw TTF. Every modern browser supports it - saving load time and bandwidth.
This tool unpacks your TTF sfnt tables and compresses them to WOFF2 locally (using the original woff2 library as WebAssembly). Glyphs, hinting, kerning and OpenType features are preserved unchanged. Nothing is uploaded - the conversion works even in airplane mode.
On the web a raw TTF slows things down needlessly: it is not compressed for transfer, and older workflows sometimes even embedded fonts as an uncompressed attachment. WOFF2 was built for exactly this purpose and is today the recommended standard for @font-face. Practical tip: if you ship a font yourself, WOFF2 alone is usually enough for modern browsers; you only still need an extra TTF or WOFF for very old environments. Also take care to embed only the weights you actually use rather than a whole family - that saves additional load time.

Limitations: The conversion is lossless: glyphs and tables are preserved, no outline optimisation happens. Only convert fonts you own or have a licence for - mind the font licence.
No. The conversion runs entirely locally in the browser, even offline.
Yes. WOFF2 wraps the same sfnt tables - no feature is lost.
Thanks to Brotli, WOFF2 is usually much smaller than the TTF, about 40-60% depending on the font.
