What formats can I convert to EOT?

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

Is EOT the best format for my use case?

Embedded OpenType (EOT) is suitable for specific use cases depending on your requirements. Choose the format that best matches your target platform and requirements.

Will conversion affect font quality?

The conversion preserves all font data including outlines, glyphs, and metrics. For WOFF/WOFF2, lossless compression is used.

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 EOT 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 EOT. 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.

About Embedded OpenType

Everything you need to know about EOT fonts

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 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 to EOT

1Why would I convert to EOT in 2024?

EOT is only needed if you must support Internet Explorer 8 or earlier. These browsers represent less than 0.1% of global traffic. Unless you're working on a legacy corporate intranet or government system locked to IE8, you should use WOFF/WOFF2 instead.

2Does EOT work in modern browsers?

No, EOT only works in Internet Explorer 6-11. It doesn't work in Chrome, Firefox, Safari, Edge (Chromium), or any mobile browser. For modern browser support, you need WOFF or WOFF2 as your primary format.

3Should I still include EOT in my @font-face?

Only if your analytics show meaningful IE8 traffic (0.5%+). For most websites, EOT is unnecessary bloat. Use WOFF2 and WOFF instead, which cover 99.9% of browsers. Check your specific audience before adding EOT support.

4How much larger is EOT than WOFF?

EOT files are typically 20-40% LARGER than WOFF due to less efficient compression and DRM overhead. This makes them slower to download and worse for performance. EOT should only be a last-resort fallback, never the primary format.

5Does EOT support OpenType features?

Limited support. Basic OpenType features work, but advanced features (stylistic sets, contextual alternates) may not render properly in older IE versions. Test thoroughly if you need advanced typography in legacy browsers.

6Can I use EOT for web apps?

Only if you absolutely must support IE8. For any modern web application, use WOFF2 with WOFF fallback. Progressive web apps (PWAs) don't need EOT since they don't support IE at all.

File Size Examples

See how file sizes change when converting to EOT

Original	Converted (EOT)	Change	Notes
150 KB (TTF)	130 KB (EOT)	-13% smaller	EOT uses LZ compression, less efficient than gzip
300 KB (TTF)	245 KB (EOT)	-18% smaller	Moderate compression from LZ algorithm
80 KB (TTF)	75 KB (EOT)	-6% smaller	Small files see minimal compression benefit
600 KB (TTF)	480 KB (EOT)	-20% smaller	Large files compress moderately

Performance Benefits

Key performance metrics for EOT format

File Size Change:10-20% smaller
EOT uses LZ compression, less efficient than WOFF/WOFF2
Browser Support:<1% users
Only works in IE6-11 (obsolete browsers)
Page Load Impact:Negative
EOT larger than WOFF2, slows down modern browsers
Conversion Necessity:Skip unless IE8
Only convert if analytics show IE6-8 users (extremely rare)
Modern Browser Performance:N/A
EOT not supported in Chrome, Firefox, Safari, modern Edge
Maintenance Cost:High
Extra format to maintain for <0.1% of users

Implementation Examples

Production-ready code for EOT fonts

Complete IE Support Stack

Full fallback chain for all browsers including IE6-8

@font-face {
    font-family: 'MyFont';
    src: url('fonts/MyFont.eot'); /* IE9 Compat Modes */
    src: url('fonts/MyFont.eot?#iefix') format('embedded-opentype'), /* IE6-IE8 */
         url('fonts/MyFont.woff2') format('woff2'), /* Modern Browsers */
         url('fonts/MyFont.woff') format('woff'), /* IE9+, Modern Browsers */
         url('fonts/MyFont.ttf') format('truetype'); /* Legacy */
    font-weight: normal;
    font-style: normal;
  }

IE8-Only Specific Targeting

Serve EOT only to IE8 using conditional comments

<!-- [if IE]>
  <link rel="stylesheet" href="ie-fonts.css">
  <![endif]-->
  
  /* In ie-fonts.css */
  @font-face {
    font-family: 'MyFont';
    src: url('fonts/MyFont.eot');
    font-weight: normal;
    font-style: normal;
  }

Troubleshooting Common Issues

Solutions to problems when converting to EOT

EOT file doesn't work in Chrome/Firefox

EOT only works in Internet Explorer. Modern browsers (Chrome, Firefox, Safari, Edge Chromium) don't support EOT. Use WOFF/WOFF2 for modern browsers. EOT should only be a fallback format listed last in your @font-face declaration for IE8 support.

EOT file is larger than the original TTF

This can happen with small fonts or fonts with specific metadata structures. EOT uses LZ compression which isn't always efficient for every font. If EOT is larger, you might have DRM/license data embedded. For web, use WOFF instead – it has better compression.

Font doesn't load in IE8/IE9

Ensure the MIME type is correct: application/vnd.ms-fontobject. Check that the @font-face rule lists EOT FIRST for IE (use ?#iefix hack). Verify file path is correct. IE is very sensitive to malformed EOT files – try a different converter if the file seems corrupt.

Converted EOT has licensing errors

EOT includes embedded license flags that some converters handle incorrectly. If you see "License violation" or embedding errors, check your original font license – it might prohibit EOT conversion. Commercial fonts often require separate web licenses.

OpenType features don't work in IE

IE has very limited OpenType feature support, especially in older versions (IE8-9). Basic features like kerning work, but advanced features (stylistic sets, contextual alternates) often fail. This is an IE limitation, not a conversion issue.

When NOT to Use EOT

Scenarios where EOT might not be the best choice

No IE6-8 users in analytics
Why not: EOT only works in IE6-11; if you have zero IE8 traffic, EOT is pointless
Use instead: Use WOFF2 + WOFF for modern browsers and IE9-11; skip EOT entirely
Modern website (2020+)
Why not: IE6-8 represent less than 0.01% of web traffic globally in 2024
Use instead: Use WOFF2 (modern) + WOFF (IE9-11); EOT adds bloat for zero users
Performance is priority
Why not: EOT is larger than WOFF and only works in dead browsers
Use instead: Skip EOT; use WOFF2/WOFF for better performance and broader support
Mobile-first site
Why not: Mobile browsers never supported EOT; it's desktop IE-only
Use instead: Use WOFF2 for optimal mobile performance; EOT is irrelevant
