Does converting WOFF to DFONT reduce quality?

Converting Web Open Font Format 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?

Converting from WOFF2/WOFF to DFONT will result in a larger file size since DFONT doesn't use compression. The file size will increase approximately 2-3x.

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 WOFF different from DFONT?

Web Open Font Format (WOFF) is a web-optimized format with gzip compression. 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+).

About This Conversion

Everything you need to know about converting between these formats

Source Format

Web Open Font Format

Target Format

macOS Datafork Font

macOS Datafork Font is a legacy Mac format that stores font data in the resource fork. It's mainly used for compatibility with older macOS systems and classic Mac applications.

Frequently Asked Questions

Common questions about converting WOFF to DFONT

1Why would I convert WOFF to DFONT?

You shouldn't. This conversion makes no sense. WOFF is a modern web format; DFONT is an obsolete Mac OS 9 format. If you need desktop fonts, convert WOFF to TTF, not DFONT. DFONT is legacy technology with no modern use case.

2Does DFONT work on modern macOS?

Barely. macOS can read DFONT files but treats them as legacy formats with limited support. Modern macOS strongly prefers TTF and OTF. Converting web fonts to DFONT is counterproductive – convert to TTF instead.

3Will I lose OpenType features converting to DFONT?

Yes, completely. DFONT predates OpenType and strips all advanced typography features. You lose ligatures, stylistic alternates, contextual features – everything that makes modern fonts sophisticated. This is a massive downgrade.

4Can DFONT be used on Windows or Linux?

No. DFONT is macOS-exclusive. Converting WOFF to DFONT destroys cross-platform compatibility. If you need desktop fonts from WOFF, convert to TTF – it works everywhere including Windows, Mac, and Linux.

5Is DFONT smaller than WOFF?

No. DFONT files are typically larger than WOFF due to uncompressed storage and resource fork overhead. WOFF is compressed web format; DFONT is uncompressed legacy desktop format. There's zero file size benefit.

6What should I convert WOFF to for desktop use?

Convert to TTF, not DFONT. TTF works on all platforms (Windows, macOS, Linux), preserves OpenType features, and has universal support in all desktop applications. DFONT is obsolete and Mac-only – avoid it completely.

7Does any modern software require DFONT?

No. All modern Mac software uses TTF and OTF. DFONT hasn't been the preferred format since Mac OS X 10.0 in 2001. If software requires DFONT in 2024, that software is critically outdated and should be replaced.

8Should I ever convert web fonts to DFONT?

This conversion path is rarely needed since it moves from a modern format to a legacy one. If you have WOFF files and need desktop fonts, convert to TTF instead. DFONT is only relevant for specific legacy macOS compatibility requirements.

Troubleshooting Common Issues

Solutions to problems you might encounter

DFONT doesn't install on modern macOS

Modern macOS (10.13+) has very limited DFONT support. Font may install with errors or not work in all apps. DFONT is obsolete (Mac OS 9). Convert WOFF to TTF instead – it works perfectly on all platforms including modern macOS.

Lost all OpenType features

DFONT predates OpenType and cannot hold modern features. All ligatures, stylistic sets, contextual alternates are stripped. If you need desktop fonts from WOFF, convert to TTF (preserves features), not DFONT (strips everything).

File size increased dramatically

WOFF is compressed; DFONT is uncompressed with resource fork overhead. A 60KB WOFF becomes approximately 120-160KB as DFONT (50-70% larger). For desktop fonts, convert to TTF instead – it's smaller and more compatible.

DFONT doesn't work on Windows

This is expected – DFONT is Mac-exclusive. For cross-platform desktop fonts from WOFF, convert to TTF. TTF works on Windows, macOS, and Linux. DFONT only works on old macOS and barely works on modern macOS.

Why would anyone do this conversion?

You shouldn't. WOFF to DFONT is a severe downgrade: web to obsolete desktop, compressed to bloated, modern features to none. If you need desktop fonts from WOFF, convert to TTF. DFONT has no modern use case.

When NOT to Use DFONT

Scenarios where you should keep WOFF or choose a different format

Cross-platform use
Why not: DFONT is Mac-exclusive; doesn't work on Windows/Linux
Use instead: Convert WOFF to TTF (universal) instead of DFONT (Mac-only)
Modern macOS
Why not: Modern macOS prefers TTF/OTF; DFONT is obsolete
Use instead: Convert WOFF to TTF for desktop; DFONT barely supported
Any modern use
Why not: DFONT from Mac OS 9 (2001); completely obsolete
Use instead: Never convert to DFONT; use TTF for desktop from WOFF
