How to convert ttf to woff2 online for free
- Step 1Drop your font file — Drag any TTF or OTF font into the converter. The file size is checked against your tier limit (5 MB free, 50 MB Pro, 1 GB Developer) before processing begins.
- Step 2Wait for WASM compression — wawoff2 instantiates its WebAssembly module on first run (about 200 ms) and then compresses the font in a Web Worker. A 5 MB CJK font compresses in under 4 seconds on a modern laptop.
- Step 3Download the WOFF2 — The result panel shows the original size, output size, and reduction percentage. Click Download — the WOFF2 file is ready to drop into your @font-face block.
Frequently asked questions
Is WOFF2 lossless?+
Yes. WOFF2 wraps the original font tables with Brotli compression and adds glyf-table preprocessing. Browsers decompress to the byte-identical sfnt at parse time — no rendering differences.
What browser support does WOFF2 have?+
Over 99% globally as of 2026. Every modern browser since Chrome 36 (2014), Firefox 39 (2015), Safari 10 (2016), and Edge 14 (2016) supports WOFF2. Only IE11 and ancient Android browsers lack support.
How does WOFF2 differ from WOFF?+
WOFF uses zlib (deflate) per table; WOFF2 uses Brotli with global dictionaries plus glyf-table preprocessing. The result is 25–35% smaller WOFF2 files with no rendering difference.
Why not just zip the TTF?+
Browsers don't auto-decompress raw zip archives for fonts. WOFF2 is a format-aware wrapper that browsers natively understand and that Brotli-compresses better than generic zip thanks to glyph-specific preprocessing.
