Can I convert commercial/licensed fonts?

Frequently Asked Questions

Common questions about converting DFONT to PFB

1Why would I convert DFONT to PFB?

Almost never. DFONT is obsolete Mac OS 9 format; PFB is obsolete PostScript print format. Both are dead technologies from the 1990s. For modern use: convert DFONT to TTF (desktop) or WOFF2 (web), not to another obsolete format.

2Does PFB work better than DFONT anywhere?

No. Both are obsolete with no modern support. DFONT is Mac-only desktop; PFB is print-only (and obsolete there). Modern equivalents: TTF (desktop), WOFF2 (web), PDF embedding (print). Don't convert between dead formats.

3Can I use PFB on modern operating systems?

Poorly or not at all. Windows 10+ and macOS 10.13+ have dropped PFB support. DFONT has better modern Mac support than PFB. For desktop fonts from DFONT, convert to TTF – it works everywhere.

4Will I lose features converting DFONT to PFB?

Both formats predate OpenType and lack modern features. You're converting from one feature-limited format to another. For modern fonts with full features: convert DFONT → TTF, add features in font editor.

5Is there any modern use for DFONT to PFB conversion?

Only for archival research or maintaining 1990s Mac/print documents in original formats. For any production use, modernize: DFONT → TTF (desktop), WOFF2 (web), PDF embedding (print). Don't use PFB.

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

For desktop: TTF (works on Windows, Mac, Linux). For web: WOFF2 + WOFF (optimal compression, broad support). For print: TTF embedded in PDF. Never convert to obsolete PFB – it has no modern advantages.

7Does PFB preserve DFONT quality?

Yes, but irrelevantly. Both can store font outlines losslessly. The problem isn't quality; it's obsolescence. Neither format is supported in modern workflows. Convert to TTF for desktop or WOFF2 for web instead.

8Should I modernize DFONT or keep it with PFB?

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

Troubleshooting Common Issues

Solutions to problems you might encounter

PFB doesn't install on modern systems

Windows 10+ and macOS 10.13+ have dropped PFB support. Font won't install. For desktop fonts from DFONT, convert to TTF – it works everywhere. PFB is obsolete (Adobe stopped development in 1999, 25 years ago).

Both formats are obsolete

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

Lost minimal features DFONT had

Both DFONT and PFB predate OpenType. Neither supports modern features. For functional fonts from DFONT: Convert to TTF or OTF (both support OpenType), not PFB (no features, no modern support).

Print software doesn't recognize PFB

Modern print workflows use TTF/OTF embedded in PDFs. PFB is obsolete even for print. For desktop/print fonts from DFONT: Convert to TTF. It works in all modern systems and print workflows.

This conversion shouldn't exist

Agreed. DFONT to PFB is converting Mac OS 9 format (obsolete 2001) to PostScript Type 1 (obsolete 1999). Both are dead. Modernize: DFONT → TTF (desktop) or WOFF2 (web). Never use PFB in 2024.

Modern systems
Why not: Both DFONT and PFB unsupported on modern OS
Use instead: Convert DFONT to TTF (modern), not PFB (obsolete)
