Sample WOFF2 File Download — Free Web Font Test Files
Download free WOFF2 test files from 10KB to 1MB with exact sizes. WOFF2 is the best font format for web — Brotli compression delivers fonts ~30% smaller than TTF/OTF with 97%+ browser support. Use these web font file downloads to test @font-face, Font Loading API, and performance.
Use cases for sample WOFF2 files
- Testing @font-face loading and font-display strategies
- Measuring web font impact on Core Web Vitals (CLS, LCP)
- Testing the CSS Font Loading API (FontFace object)
- Verifying font preloading with <link rel='preload'>
- Benchmarking WOFF2 vs TTF download and parsing times
- Testing font CDN caching and cache-control headers
Optimal web font loading
<!-- 1. Preload critical font (above the fold) -->
<link rel="preload" href="/fonts/main.woff2"
as="font" type="font/woff2" crossorigin>
<!-- 2. CSS @font-face with font-display: swap -->
<style>
@font-face {
font-family: 'MainFont';
src: url('/fonts/main.woff2') format('woff2');
font-weight: 400;
font-style: normal;
font-display: swap;
}
</style>
<!-- 3. JavaScript Font Loading API (programmatic) -->
<script>
const font = new FontFace('MainFont',
'url(/fonts/main.woff2)');
font.load().then(() => {
document.fonts.add(font);
document.body.classList.add('fonts-loaded');
});
