WOFF2 is the gold standard for web font delivery, using Brotli compression to achieve 30-50% smaller files than the original OTF. Convert your OpenType fonts with the MyPDF OTF to WOFF2 converter and deliver typography that loads fast on every device.

How to Convert OTF to WOFF2

  1. Upload — Drop your .otf font file into the converter.
  2. Convert — Brotli compression is applied automatically, producing a compact WOFF2 file.
  3. Download — Save the .woff2 file and add it to your project's font directory.

Practical Tips

  • List WOFF2 first in @font-face. Browsers pick the first supported format, so WOFF2 should appear before WOFF and TTF fallbacks.
  • Combine with subsetting. Remove unused character ranges using the Font Subset tool before converting for the smallest possible file.
  • Check metadata. Use the Font Metadata viewer to verify licence and naming fields survive the conversion.

Does WOFF2 support variable fonts?

Yes. WOFF2 can wrap variable OpenType fonts with full axis support. The Brotli compression is especially effective on variable font tables.

Will converting to WOFF2 degrade font quality?

No. WOFF2 is a lossless container — all glyph outlines, hinting instructions, and OpenType features are preserved exactly.

What about Internet Explorer support?

IE does not support WOFF2. Include a WOFF fallback in your @font-face stack with the OTF to WOFF converter to cover older browsers.
