Convert TrueType (TTF) to WOFF2 Online Free
Convert TrueType fonts to WOFF2 for the smallest possible web font files. WOFF2 uses Brotli compression to achieve significantly better compression than WOFF, making it the modern standard for serving fonts on the web.
By ChangeThisFile Team · Last updated: March 2026
To convert TTF to WOFF2, drop your .ttf file onto the ChangeThisFile converter. The font is compressed using Brotli encoding entirely in your browser — no upload needed. WOFF2 delivers 30-50% better compression than WOFF, making it the preferred web font format. Completely free and private.

TrueType (TTF) vs WOFF2: Format Comparison
Key differences between the two formats
| Feature | TrueType (TTF) | WOFF2 |
|---|---|---|
| Compression | None (uncompressed outlines) | Brotli (best-in-class for fonts) |
| Typical file size | 100% (baseline) | ~40-60% of original TTF size |
| Browser support | All browsers via @font-face | All modern browsers (95%+ global) |
| Primary use | Desktop and OS installation | Modern web font delivery |
| Hinting | Full TrueType hinting | Hinting preserved, optional preprocessing |
| Metadata | Standard OpenType tables | Optional extended metadata block |
| Spec version | Apple/Microsoft standard since 1990s | W3C Recommendation since 2018 |
When to Convert
Common scenarios where this conversion is useful
Maximizing web performance scores
WOFF2 is the smallest web font format available. Converting TTF to WOFF2 minimizes font payload size, directly improving Largest Contentful Paint and overall Core Web Vitals.
Serving custom brand fonts on high-traffic sites
For sites serving millions of page views, the bandwidth savings from WOFF2 vs. raw TTF add up significantly. Every kilobyte saved per request reduces CDN costs.
Building a modern @font-face stack
Best practice is to serve WOFF2 as the primary format with WOFF as fallback. Convert your TTF source files to both formats for complete browser coverage.
Progressive web app font optimization
PWAs benefit from small asset sizes for offline caching. WOFF2 fonts take less storage in the service worker cache and load faster on repeated visits.
Reducing font loading latency on mobile
Mobile connections benefit most from smaller files. WOFF2 compression means fonts arrive faster on 3G/4G networks, reducing flash of unstyled text (FOUT).

-
2
Instant conversion
Your font is parsed and compressed with Brotli encoding entirely in the browser using opentype.js. All glyphs, kerning, hinting, and OpenType features are preserved.

Download your WOFF2 file
Click Download to save the compressed .woff2 file. Reference it in your CSS @font-face rules with format('woff2') for optimal web delivery.
Frequently Asked Questions
WOFF2 typically reduces font file size by 40-60% compared to the original TTF. For example, a 200KB TTF font might compress to 80-120KB as WOFF2, thanks to Brotli's font-specific compression.
Yes. WOFF2 is a lossless compression format. All glyph outlines, hinting instructions, kerning pairs, and OpenType features are preserved exactly as in the original TTF.
WOFF2 is supported by Chrome 36+, Firefox 39+, Safari 12+, Edge 14+, and Opera 23+. This covers over 95% of global browser usage. Only IE11 and very old mobile browsers lack support.
For maximum compatibility, include both. WOFF2 is served to modern browsers (vast majority), and WOFF serves as fallback. If you only support modern browsers, WOFF2 alone is sufficient.
Yes. Variable font tables (fvar, gvar, STAT, etc.) are preserved during conversion. Your WOFF2 output will support the same axes and instances as the original TTF variable font.
No. TrueType hinting instructions are fully preserved in the WOFF2 output. WOFF2 can optionally apply hinting preprocessing for better compression, but glyph rendering remains identical.
No. The conversion runs entirely in your browser using JavaScript. Your font data never leaves your device, making it safe for licensed and proprietary fonts.
The converter processes one file at a time. If you have separate TTF files for Regular, Bold, Italic, etc., convert each one individually to get the corresponding WOFF2 files.
Brotli is a compression algorithm developed by Google, optimized for web content. For fonts specifically, WOFF2 uses a font-aware preprocessing step before Brotli compression, achieving better ratios than general-purpose compression.
Use @font-face with the src property: src: url('font.woff2') format('woff2'). Place the WOFF2 source first in the src list so browsers that support it will use it preferentially.
