Does converting TTF to EOT reduce quality?

Converting TrueType Font 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?

File size changes depend on the specific conversion from TrueType Font to Embedded OpenType. EMBEDDED OPENTYPE files may be larger or smaller depending on the format's structure and metadata.

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 TTF different from EOT?

TrueType Font (TTF) is a widely-supported format with quadratic Bézier curves. 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

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

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 TTF 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 TTF 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.

7What's the best @font-face setup with EOT?

List formats in order: WOFF2 (modern browsers), WOFF (IE9-11 + older browsers), EOT (IE6-8 only). Put EOT last in the src list. This ensures modern browsers get the best format while legacy browsers still work.

8Are there licensing issues with EOT?

EOT includes Microsoft's font DRM system, which some font licenses prohibit. Check if your font license allows EOT conversion. Many foundries require separate web font licenses even if you already have a desktop license.

Implementation Examples

Production-ready code for your converted 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;
  }

Modern Stack with EOT Fallback

Prioritize modern formats, EOT as last resort

@font-face {
    font-family: 'Corporate Font';
    src: url('fonts/Corporate.eot?#iefix') format('embedded-opentype'),
         url('fonts/Corporate.woff2') format('woff2'),
         url('fonts/Corporate.woff') format('woff');
    font-weight: 400;
    font-display: swap;
  }

Troubleshooting Common Issues

Solutions to problems you might encounter

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 you should keep TTF or choose a different format

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
Any use case in 2024
Why not: EOT is completely obsolete; all IE versions are unsupported by Microsoft
Use instead: Never create new EOT files; use WOFF2 + WOFF instead
