See your font in any size, weight, and sample text — instantly.
How it works
opentype.js plus harfbuzz-wasm for parsing and subsetting; WOFF2 round-trip support. The processing code runs inside the page, so your file is not uploaded to a server — you can confirm this in your browser's DevTools → Network tab.
