What formats can I convert to WOFF2?

You can convert from any major font format including TTF, OTF, WOFF, WOFF2, EOT, SVG, DFont, and PFB to WOFF2. Our converter automatically detects the source format.

Is WOFF2 the best format for my use case?

Web Open Font Format 2 (WOFF2) is the most efficient format for modern web use with smallest file sizes. Choose the format that best matches your target platform and requirements.

Will conversion affect font quality?

Converting to WOFF2 uses lossless compression, so the font outlines and glyphs remain identical. Only the file size changes.

Can I convert multiple fonts at once?

Yes, use our batch conversion feature to upload multiple font files and convert them all to your target format simultaneously. You can also export to multiple formats at once.

What CSS code will I get?

We automatically generate @font-face CSS code for your WOFF2 files. This includes proper format declarations and fallbacks for optimal browser support.

Will my font's OpenType features work after conversion?

Yes, all OpenType features are preserved during conversion to WOFF2. 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 doesn't automatically grant web usage rights. Always check your license agreement or contact the foundry.

Frequently Asked Questions

Common questions about converting 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 your font?

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.

File Size Examples

80 KB (TTF)	35 KB (WOFF2)	-56% smaller	Even small fonts see significant reduction
600 KB (TTF)	180 KB (WOFF2)	-70% smaller	Extended character sets compress excellently

Troubleshooting Common Issues

Solutions to problems when converting to WOFF2

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 WOFF2 might not be the best choice

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
