What formats can I convert to DFONT?

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

Is DFONT the best format for my use case?

macOS Datafork Font (DFONT) 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 DFONT 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 DFONT. 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.

Frequently Asked Questions

Common questions about converting to DFONT

1Why would I convert your font to DFONT?

DFONT is only needed for legacy macOS systems (Mac OS 9 and earlier). Modern macOS uses TTF and OTF natively. Only convert to DFONT if you're supporting very old Mac software or archiving fonts for classic Mac applications.

2Does DFONT work on modern macOS?

macOS can still read DFONT files, but there's no advantage. Modern macOS (10.0+) prefers TTF and OTF. Keep your TTF files – they work better on all current systems. DFONT is purely for legacy compatibility.

3Will converting to DFONT improve compatibility?

No, the opposite. DFONT only works on macOS and doesn't work on Windows or Linux at all. TTF works universally across all platforms. Converting to DFONT reduces compatibility, not improves it.

4Can I use DFONT on websites?

No. DFONT is not a web font format and no browsers support it. For web use, convert to WOFF2 or WOFF instead. DFONT is exclusively for macOS desktop applications.

5Does DFONT support OpenType features?

No. DFONT is a legacy format from before OpenType existed. Advanced typography features like ligatures, stylistic sets, and contextual alternates won't work. Keep TTF for modern font features.

6Is DFONT smaller than your font?

No, DFONT files are similar in size to TTF, sometimes larger due to resource fork overhead. There's no compression benefit. If you need smaller files, convert to WOFF2 for web use instead.

Troubleshooting Common Issues

Solutions to problems when converting to DFONT

DFONT doesn't install on modern macOS

Modern macOS (10.13+) has limited DFONT support. The font may install but not work properly in all applications. Convert to TTF instead – it works perfectly on modern macOS and is the preferred format. DFONT is obsolete technology.

DFONT doesn't work on Windows

This is expected – DFONT is Mac-only and will never work on Windows. If you need cross-platform fonts, use TTF (works everywhere), not DFONT (Mac-only). There's no workaround; DFONT is fundamentally incompatible with Windows.

Lost OpenType features after conversion

DFONT predates OpenType and cannot hold advanced features. All ligatures, stylistic sets, and contextual alternates are stripped during conversion. This is a DFONT limitation. If you need modern features, keep TTF or convert to OTF, not DFONT.

File size increased significantly

DFONT has resource fork overhead that can make files larger than TTF. This is normal. DFONT offers no file size benefit. If size matters, keep your TTF files or convert to WOFF2 for web (60-70% compression).

Why would I even want DFONT?

You probably don't. DFONT is obsolete (Mac OS 9 era). Unless you're supporting legacy Mac systems from before 2001, there's zero reason to convert to DFONT. Use TTF for modern macOS – it works better and has universal compatibility.

When NOT to Use DFONT

Scenarios where DFONT might not be the best choice

Cross-platform use
Why not: DFONT is Mac-exclusive and doesn't work on Windows or Linux
Use instead: Keep TTF - it works on all platforms including modern macOS
Modern macOS (10.13+)
Why not: Modern macOS prefers TTF/OTF; DFONT is legacy format with limited support
Use instead: Use TTF for modern macOS; it works better than obsolete DFONT
You need OpenType features
Why not: DFONT predates OpenType and strips all modern font features
Use instead: Keep TTF to preserve ligatures, stylistic sets, and all OpenType features
Web deployment
Why not: DFONT has never worked on the web and never will
Use instead: Convert TTF to WOFF2 for web; DFONT is desktop-only (and obsolete)
