Does converting TTF to WOFF2 reduce quality?

No, converting TTF to WOFF2 does not reduce quality. WOFF2 uses lossless compression, meaning the font outlines, glyphs, and visual appearance remain identical to the original. Only the file size changes.

What file size reduction should I expect?

You can expect a file size reduction of 50-70% when converting TTF to WOFF2. For example, a 150KB TRUETYPE FONT file typically compresses to around 45-75KB as WOFF2 due to Brotli compression.

Do WOFF2 fonts work in all browsers?

WOFF2 works in all modern browsers: Chrome 36+, Firefox 62+, Safari 11.1+, and Edge (all versions). It's not supported in IE11 or older browsers.

Will my font's OpenType features work after conversion?

Yes, all OpenType features are preserved during conversion. This includes ligatures, kerning pairs, alternate glyphs, small caps, and other advanced typography features. The conversion process adapts the container format while preserving all font data.

Can I convert commercial/licensed fonts?

You can convert commercial fonts for testing purposes, but you must purchase the appropriate web font license before using them on a live website. Font licenses are format-specific – a desktop license for one format doesn't automatically grant web usage rights. Always check your license agreement or contact the foundry.

How is TTF different from WOFF2?

TrueType Font (TTF) is a widely-supported format with quadratic Bézier curves. Web Open Font Format 2 (WOFF2) is the most efficient web format with Brotli compression. Choose based on your target platform and requirements.

What's the best format for my use case?

For modern websites, use WOFF2 as your primary format. Provide WOFF as a fallback for older browsers. For desktop applications, consider TTF or OTF.

Can I convert variable fonts?

Yes, variable fonts can be converted between formats while preserving all variation axes and design space. The conversion maintains the font's interpolation capabilities. Ensure your target browsers support variable fonts (Chrome 62+, Firefox 62+, Safari 11+).

About This Conversion

Everything you need to know about converting between these formats

Source Format

TrueType Font

TrueType Font (TTF) is a widely-used font format developed by Apple and Microsoft. It's supported across all major operating systems and is commonly used for desktop applications. TTF files contain both the font outline data and bitmap data.

Target Format

Web Open Font Format 2

WOFF2 is an improved version of WOFF with better Brotli compression, resulting in 30% smaller file sizes than WOFF. It's the preferred format for modern web applications and provides faster page load times.

Frequently Asked Questions

Common questions about converting TTF to WOFF2

1Why is WOFF2 better than WOFF?

WOFF2 uses Brotli compression instead of gzip, resulting in 25-30% smaller files than WOFF. For a 100KB WOFF file, the WOFF2 version would be around 70-75KB. This translates to faster page loads, reduced bandwidth costs, and improved Core Web Vitals scores.

2Does WOFF2 work in Internet Explorer?

No, WOFF2 is not supported in any version of Internet Explorer, including IE11. If you need IE support, you must provide WOFF or EOT as a fallback format in your @font-face declaration. List WOFF2 first, followed by WOFF for legacy browser support.

3Should I use WOFF2 or WOFF?

Use both! Provide WOFF2 as the primary format for modern browsers, with WOFF as a fallback for older browsers. List WOFF2 first in your @font-face src, and browsers will automatically use the first format they support. This gives you maximum compression while maintaining compatibility.

4What browsers support WOFF2?

WOFF2 is supported in Chrome 36+, Firefox 39+, Safari 10+, Edge 14+, Opera 23+, and all mobile browsers from 2016 onwards. It has excellent support covering 95%+ of current web traffic, but no support in IE11 or earlier.

5Does converting to WOFF2 affect font quality?

No, WOFF2 uses lossless compression just like WOFF. The visual quality, OpenType features, hinting, and kerning are all preserved perfectly. Only the file size changes – all font data remains identical to the original.

6How much smaller is WOFF2 than TTF?

WOFF2 is typically 60-70% smaller than the original TTF file. For example, a 200KB TTF becomes approximately 60-80KB as WOFF2. This is significantly better than WOFF's 40-60% reduction and dramatically improves page load performance.

7Can I use only WOFF2 without WOFF fallback?

Yes, if you're okay with dropping support for IE11 and very old browsers. Check your analytics – if IE11 traffic is less than 1%, you can safely use WOFF2-only. Most modern websites now serve WOFF2 exclusively with system font fallbacks.

8Do variable fonts work with WOFF2?

Yes, variable fonts work perfectly with WOFF2 and benefit greatly from the superior compression. Variable fonts are already large files due to containing multiple weights/styles, so WOFF2's extra compression (25-30% over WOFF) makes a significant difference in load times.

Troubleshooting Common Issues

Solutions to problems you might encounter

Font not working in Internet Explorer

WOFF2 is completely unsupported in all IE versions. Provide WOFF or EOT as fallback. In your @font-face, list formats: WOFF2 (modern browsers), then WOFF (IE9-11), then EOT (IE8). Browsers use the first format they support.

File size isn't much smaller than WOFF

Some fonts compress better than others. Simple fonts with few glyphs (<500 characters) see less compression benefit. For additional savings, subset the font to remove unused characters, punctuation, or non-Latin scripts you don't need.

Variable font lost variation axes

Ensure you're using a converter that explicitly supports variable fonts. Not all conversion tools preserve variable font data. Check if the original TTF is truly a variable font using a font inspector tool. Variable fonts require specific handling during compression.

Browser shows fallback font briefly (FOIT)

Add font-display: swap to your @font-face to show fallback text immediately while font loads. Alternatively, use font-display: optional for optional fonts. Consider using <link rel="preload"> for above-the-fold fonts to load them earlier in the page render.

CORS error when loading from CDN

WOFF2 requires proper CORS headers for cross-origin requests. Configure your CDN to send: Access-Control-Allow-Origin: * (or specify your domain). This is a CDN configuration issue, not a font conversion issue. Check your CDN documentation for CORS setup.

When NOT to Use WOFF2

Scenarios where you should keep TTF or choose a different format

Must support IE11
Why not: IE11 doesn't support WOFF2; you need WOFF fallback for those users
Use instead: Create both WOFF2 (modern) and WOFF (IE11 fallback) versions
Desktop application use
Why not: WOFF2 is web-only; desktop software cannot use WOFF2 files
Use instead: Keep TTF for desktop; convert to WOFF2 only for web deployment
Email templates
Why not: Email clients don't support WOFF2 or web fonts in general
Use instead: Use system fonts for email; WOFF2 doesn't work in most email clients
Font editing workflow
Why not: WOFF2 is a delivery format; editing software needs TTF source files
Use instead: Maintain TTF as source; generate WOFF2 for production web use only
Legacy browser support required
Why not: Older browsers (Safari 9-, Android 4.4-) don't support WOFF2
Use instead: Provide both WOFF2 (modern) and WOFF (legacy) for full coverage
