Technical Specifications & Codec Breakdown
Why You Should Always Use WOFF2 on the Web
TTF and OTF were built for desktop operating systems and contain uncompressed glyph tables. WOFF2 applies custom table preprocessing and Brotli compression, shrinking font files by up to 50% without altering a single curve, drastically improving page load speed and layout stability.
Converting Desktop Fonts for Web Performance
If your site loads a 150 KB desktop TTF font, visitors on mobile may experience invisible text or layout shifts while downloading. Converting to WOFF2 reduces the file to ~40 KB, rendering typography instantly.
