Does converting PFB to DFONT reduce quality?

Converting PostScript Type 1 to macOS Datafork Font 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 macOS Datafork Font. MACOS DATAFORK FONT files may be larger or smaller depending on the format's structure and metadata.

Do DFONT fonts work in all browsers?

DFont is a macOS-specific format not supported by web browsers. Convert to WOFF/WOFF2 for web use.

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 DFONT?

PostScript Type 1 (PFB) is a font format with specific use cases. macOS Datafork Font (DFONT) 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, DFONT 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+).

Frequently Asked Questions

Common questions about converting PFB to DFONT

1Why would I convert PFB to DFONT?

Almost never. PFB is obsolete PostScript print format; DFONT is obsolete Mac OS 9 desktop format. Both are dead. For modern use: convert PFB to TTF (desktop on all platforms) or WOFF2 (web), not to another obsolete format.

2Does DFONT work better than PFB anywhere?

No. Both are obsolete with minimal modern support. PFB barely works on modern OS; DFONT barely works on modern macOS. Modern equivalents: TTF (desktop), WOFF2 (web). Don't convert between dead formats.

3Can DFONT be used on modern macOS?

Barely. macOS can read DFONT but treats it as legacy. Modern macOS strongly prefers TTF and OTF. For desktop fonts from PFB, convert to TTF – it works on Mac, Windows, and Linux.

4Will I lose features converting PFB to DFONT?

PFB has limited features; DFONT has even fewer (predates OpenType). You're converting from one limited format to another. For modern fonts with full features: convert PFB → TTF, then add features in font editor.

5Does DFONT work on Windows or Linux?

No. DFONT is Mac-exclusive. Converting PFB (already barely supported) to DFONT (Mac-only) destroys what little compatibility you had. Convert to TTF instead – it works on all platforms.

6What's the best format to convert PFB to?

For desktop: TTF (works on Windows, Mac, Linux). For web: WOFF2 + WOFF (optimal compression, broad support). Never convert to obsolete DFONT or EOT. Use modern formats for better compatibility.

7Is there any modern use for PFB to DFONT conversion?

Only for archival research or maintaining 1990s documents that require both PostScript and Mac OS 9 formats. For any production use, modernize: PFB → TTF (desktop), WOFF2 (web). Don't use DFONT.

8Should I modernize PFB or keep it with DFONT?

Modernize! Convert PFB to TTF (desktop on all platforms) and WOFF2 (modern web). Both PFB and DFONT are obsolete formats that hurt compatibility and lack features. Use current standards: TTF and WOFF2.

Troubleshooting Common Issues

Solutions to problems you might encounter

DFONT doesn't work on modern macOS

Modern macOS (10.13+) has very limited DFONT support. DFONT is obsolete (Mac OS 9 era). For desktop fonts from PFB, convert to TTF instead – it works on all platforms including modern macOS. Don't use DFONT.

Both formats are obsolete

PFB (PostScript Type 1, obsolete 1999) and DFONT (Mac OS 9, obsolete 2001) are both dead. For modern use from PFB: Convert to TTF (universal desktop) or WOFF2 (modern web). Don't convert between obsolete formats.

PostScript curves degraded to older format

DFONT doesn't properly support PostScript outlines. You lose the curve quality that PFB had. For modernizing PFB: Convert to TTF (compatible) or OTF with CFF (preserves PostScript), not DFONT (degrades everything).

DFONT doesn't work on Windows

This is expected – DFONT is Mac-exclusive. For cross-platform fonts from PFB, convert to TTF. TTF works on Windows, macOS, and Linux. Converting PFB to DFONT trades print-only for Mac-only. Use TTF for universal compatibility.

This conversion is absurd

Agreed. PFB to DFONT converts PostScript print font (obsolete 1999) to Mac desktop font (obsolete 2001). Both are dead with no modern support. Modernize: PFB → TTF (desktop) or WOFF2 (web). Never use DFONT in 2024.

When NOT to Use DFONT

Scenarios where you should keep PFB or choose a different format

Cross-platform use
Why not: DFONT Mac-only; PFB was cross-platform (though obsolete)
Use instead: Convert PFB to TTF (universal) not DFONT (Mac-only)
Modern systems
Why not: Both PFB and DFONT unsupported on modern OS
Use instead: Convert PFB to TTF (modern), not DFONT (obsolete)
Any use in 2024
Why not: Both obsolete; don't convert between dead formats
Use instead: Convert PFB to TTF or WOFF2, never DFONT
