Does converting WOFF2 to EOT reduce quality?

Converting Web Open Font Format 2 to Embedded OpenType preserves all font data including outlines, glyphs, and metrics. The conversion maintains the integrity of your font while adapting it for the target format.

What file size reduction should I expect?

Converting from WOFF2/WOFF to EOT will result in a larger file size since EOT doesn't use compression. The file size will increase approximately 2-3x.

Do EOT fonts work in all browsers?

EOT is only supported by Internet Explorer browsers (IE6-IE11). No other browsers support EOT natively.

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 WOFF2 different from EOT?

Web Open Font Format 2 (WOFF2) is a web format with superior Brotli compression. Embedded OpenType (EOT) is a format for specific applications. Choose based on your target platform and requirements.

What's the best format for my use case?

For web use, convert to WOFF2 or WOFF instead. For desktop applications or print, EOT may be appropriate. Always check the requirements of your target platform.

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

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.

Target Format

Embedded OpenType

Embedded OpenType (EOT) is a Microsoft format primarily used for older Internet Explorer browsers (IE6-IE8). It includes DRM features but is largely obsolete with modern browsers supporting WOFF/WOFF2.

Why Convert WOFF2 to EOT?

Supporting Internet Explorer 6-8 browsers

Maintaining compatibility with legacy corporate systems

Working on projects requiring old browser support

Converting historical web font implementations

Frequently Asked Questions

Common questions about converting WOFF2 to EOT

1Why would I convert WOFF2 to EOT?

You almost never should. WOFF2 supports modern browsers; EOT only supports IE6-8 (under 0.01% of traffic). If you need IE compatibility, convert WOFF2 to WOFF (for IE9-11), not EOT. EOT is obsolete except for ancient IE versions.

2Does EOT work in any browser that doesn't support WOFF2?

Only IE6-8. IE9-11 support WOFF (not WOFF2). Modern browsers that don't support WOFF2 (none exist in 2024) would support WOFF. EOT only adds support for browsers from 2001-2009, which are completely extinct.

3Should I include both WOFF2 and EOT in @font-face?

No. Better strategy: WOFF2 (modern browsers) + WOFF (IE9-11). Skip EOT entirely unless your analytics show IE6-8 traffic, which is vanishingly rare in 2024. EOT adds complexity for zero practical benefit.

4Will converting WOFF2 to EOT increase file size?

Yes, dramatically. A 70KB WOFF2 becomes approximately 180-220KB as EOT (60-70% larger). EOT's LZ compression is far inferior to WOFF2's Brotli. There's no scenario where EOT performs better than WOFF2.

5Can EOT support features better than WOFF2?

No, the opposite. EOT has severely limited OpenType support compared to WOFF2. Advanced features may not work in IE even with EOT. WOFF2 fully preserves all features, while EOT has significant limitations.

6What's the best font stack for maximum compatibility?

WOFF2 (95%+ of users) + WOFF (IE9-11, maybe 1% of users). Skip EOT. This covers 99.9% of browsers. Adding EOT for the remaining 0.01% (IE6-8) is wasted effort – those users expect broken websites anyway.

7Does converting WOFF2 to EOT lose quality?

The basic font data is preserved, but OpenType features may degrade due to IE's limited support. However, this is moot – don't use EOT at all. If you have WOFF2, your IE coverage should be WOFF, not EOT.

8Is there any valid reason to convert WOFF2 to EOT in 2024?

Only if maintaining a legacy corporate intranet locked to Windows XP/IE6 that cannot be upgraded. For any public-facing site or modern environment, skip EOT completely. Use WOFF2 + WOFF instead.

Troubleshooting Common Issues

Solutions to problems you might encounter

EOT file is 60-70% larger than WOFF2

This is expected. WOFF2 uses cutting-edge Brotli compression; EOT uses obsolete LZ compression. A 70KB WOFF2 becomes approximately 180-220KB as EOT. This massive increase is one more reason to skip EOT entirely.

Why would I do this conversion?

You almost never should. WOFF2 supports modern browsers; EOT only supports IE6-8 (under 0.01% of traffic). Better strategy: Convert WOFF2 to WOFF for IE9-11 support. Skip EOT completely unless you have confirmed IE6-8 users (virtually impossible).

EOT doesn't work in modern browsers

This is expected. EOT only works in IE6-11. Modern browsers use WOFF2 or WOFF. For browser compatibility: WOFF2 (modern, 95%+) + WOFF (IE9-11, ~1%). Skip EOT unless supporting IE6-8 (0.01% of traffic).

Conversion fails with licensing error

EOT includes DRM/license flags. Some converters can't create EOT if license data is incompatible. Check your font license – commercial fonts may prohibit EOT conversion. Also, consider whether IE6-8 support is even necessary (it almost never is).

OpenType features don't work in IE

IE has severely limited OpenType support. Advanced features fail even with proper EOT files. This is an IE limitation, not a conversion issue. Modern browsers with WOFF2 have full OpenType support.

When NOT to Use EOT

Scenarios where you should keep WOFF2 or choose a different format

No IE6-8 traffic
Why not: EOT only for IE6-8 which is <0.01% of users
Use instead: Use WOFF2 + WOFF; skip obsolete EOT entirely
Modern website
Why not: EOT is 2-3x larger than WOFF2 for essentially zero users
Use instead: Use WOFF2 + WOFF for IE9-11; skip EOT
Performance priority
Why not: EOT is massive compared to WOFF2 and only works in dead browsers
Use instead: Never create EOT; use WOFF2 + WOFF only
Any use in 2024
Why not: EOT completely obsolete; all IE versions unsupported
Use instead: Skip EOT entirely; WOFF2 + WOFF covers everyone
