Does converting PFB to EOT reduce quality?

Converting PostScript Type 1 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 PostScript Type 1 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 PFB different from EOT?

PostScript Type 1 (PFB) is a font format with specific use cases. 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

PostScript Type 1

PostScript Type 1 Binary (PFB) is an Adobe font format used primarily for professional printing. It offers high-quality rendering and was the standard for desktop publishing before TrueType and OpenType became dominant.

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 PFB 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 PFB to EOT

1Why would I convert PFB to EOT?

Not recommended. Both PFB and EOT are legacy formats from the 1990s-2000s with limited modern support. For web fonts from PFB, convert to WOFF2/WOFF. For desktop, convert to TTF. EOT is only needed for IE8 support (under 0.01% of traffic).

2Which is more obsolete: PFB or EOT?

Both are equally dead. PFB is PostScript Type 1 (obsolete 1999); EOT is IE6-11 only (obsolete 2022). Neither has modern use cases. Modernize: PFB → TTF (desktop), WOFF2/WOFF (web). Don't convert between obsolete formats.

3Does EOT work better than WOFF for PFB fonts?

No. EOT only works in IE6-11 (dead browsers). WOFF works in all browsers from 2015+. For PFB modernization: PFB → TTF → WOFF2 (modern) + WOFF (IE9-11). Skip EOT unless you have IE6-8 users.

4Can EOT preserve PostScript outlines from PFB?

EOT typically converts PostScript to TrueType. Both EOT and modern formats (WOFF2) do this conversion. The difference is: EOT only works in IE; WOFF2 works everywhere and is 60-70% smaller. Use WOFF2, not EOT.

5Should I create EOT from PFB for legacy support?

Only if analytics show IE6-8 traffic (virtually nonexistent). Better strategy: PFB → TTF → WOFF2 (95% of users) + WOFF (IE9-11, ~1%). Skip EOT for the remaining 0.01% – they expect broken websites.

6Can I skip EOT entirely when modernizing PFB?

Yes! For 99.99% of sites: PFB → TTF → WOFF2 + WOFF. This covers all modern browsers and IE9-11. EOT adds complexity for essentially zero users. Only create EOT if confirmed IE6-8 traffic exists.

7What's the best format to convert PFB to?

For desktop: TTF (universal compatibility, full OpenType). For web: WOFF2 + WOFF (modern compression, broad support). Never convert between obsolete formats (PFB ↔ EOT). Modernize to current standards.

8Is there any scenario where PFB to EOT makes sense?

Only maintaining a time capsule website supporting both 1990s print fonts and IE6-8 simultaneously. This doesn't exist in 2024. For any real use, modernize: PFB → TTF (desktop), WOFF2 (web). Skip both PFB and EOT.

Troubleshooting Common Issues

Solutions to problems you might encounter

Why convert between obsolete formats?

You shouldn't. Both PFB (PostScript Type 1, obsolete 1999) and EOT (IE6-11, obsolete 2022) are dead. For modern use from PFB: Convert to TTF (desktop) or WOFF2/WOFF (web). Don't convert between obsolete formats.

Requires intermediate conversion

Workflow: PFB → TTF → EOT. However, question whether you need EOT. It only supports IE6-11 (obsolete). Better: PFB → TTF → WOFF2/WOFF for modern browsers. Skip EOT unless you need IE8 (virtually extinct).

Both formats have limited features

PFB has no OpenType features; EOT has limited support. You're converting between feature-limited dead formats. For modern use: Convert PFB to TTF (full OpenType support), not EOT (limited features for dead browsers).

PostScript curves lost

EOT doesn't support PostScript curves. They convert to TrueType. If you care about preserving PostScript, don't use EOT. For modern use: PFB → OTF with CFF (desktop) or WOFF2 (web). EOT destroys curve format anyway.

This makes no sense

Correct. PFB to EOT converts PostScript print font (obsolete 1999) to IE web font (obsolete 2022). Both are dead. Modernize: PFB → TTF (desktop) or WOFF2 (web). Don't use obsolete formats in 2024.

When NOT to Use EOT

Scenarios where you should keep PFB or choose a different format

No IE6-8 users
Why not: EOT only for IE6-8 which is <0.01% of users
Use instead: Convert PFB to WOFF2/WOFF; skip obsolete EOT
Modern website
Why not: Both PFB and EOT obsolete
Use instead: Convert PFB to WOFF2 + WOFF, not EOT
Any use in 2024
Why not: Both formats obsolete; don't convert between them
Use instead: Convert PFB to TTF or WOFF2, never EOT
