Web font optimization & @font-face tips

Converting desktop font files (TTF/OTF) into modern web fonts (WOFF2) is one of the most effective ways to speed up website load times:

Brotli compression: WOFF2 uses built-in Brotli compression algorithms to achieve 30% to 50% smaller file sizes than standard TrueType (TTF) or OpenType (OTF) fonts.
Browser compatibility: All modern browsers (Chrome, Edge, Safari, Firefox) natively support WOFF2. Keep a TTF fallback only if supporting legacy browsers.
CSS Implementation: Define your converted font using the standard @font-face CSS rule with font-display: swap; to prevent layout shifts.
Client-side security: Your font files are converted directly in your browser using WebAssembly. Proprietary brand fonts are never uploaded to third-party servers.

Frequently Asked Questions

Q: Why is WOFF2 better for websites than TTF or OTF?
A: WOFF2 files are significantly smaller, reducing page download times and preventing invisible text flashes (FOIT) on mobile networks.

Q: Can I convert commercial fonts safely?
A: Yes. Because processing occurs entirely in your browser's local memory, your font files are never stored or shared.

Q: How do I load the converted WOFF2 file in CSS?
A: Use @font-face { font-family: 'MyFont'; src: url('myfont.woff2') format('woff2'); font-display: swap; }.
