WOFF2 (Web Open Font Format 2) is a modern web font format with improved compression. It provides a 30% size reduction compared to WOFF and 50% compared to TTF/OTF. This significantly speeds up page loading and improves site performance.
Converting fonts to WOFF2 is a mandatory step in web project optimization. Smaller file sizes mean faster loading, user traffic savings, and better Google PageSpeed scores. WOFF2 has been supported by all modern browsers since 2016.
Our converter works completely online without software installation. Upload a TTF, OTF or WOFF file, get an optimized WOFF2 in seconds. All files are processed on the server and not saved after conversion.
How do I convert several fonts to WOFF2 at once?
Upload multiple TTF/OTF/WOFF files via the select button or drag and drop — after conversion, a "Download All" button appears for batch download in a ZIP archive.
Do I need to convert to WOFF2 if my site already uses WOFF?
Not strictly, but it's worth it: WOFF2 is typically about 30% lighter than WOFF for the same font, and browser support has been near-universal since 2016 — the switch is almost always a clean win for load speed.
What about older browsers that don't support WOFF2?
Include WOFF as a fallback via @font-face with multiple src entries — the browser picks WOFF2 if supported and falls back to WOFF otherwise.
