Does converting DFONT to WOFF reduce quality?

No, converting DFONT to WOFF does not reduce quality. WOFF uses lossless compression, meaning the font outlines, glyphs, and visual appearance remain identical to the original. Only the file size changes.

What file size reduction should I expect?

You can expect a file size reduction of 40-60% when converting DFONT to WOFF. For example, a 150KB MACOS DATAFORK FONT file typically compresses to around 60-90KB as WOFF due to gzip compression.

Do WOFF fonts work in all browsers?

WOFF fonts work in all modern browsers and most older ones. Support includes Chrome 36+, Firefox 39+, Safari 5.1+, Edge (all versions), and Internet Explorer 9+.

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 DFONT different from WOFF?

macOS Datafork Font (DFONT) is a font format with specific use cases. Web Open Font Format (WOFF) is a web format with broad browser support. Choose based on your target platform and requirements.

What's the best format for my use case?

For modern websites, use WOFF as your primary format. Provide WOFF as a fallback for older browsers. For desktop applications, consider TTF or OTF.

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

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.

Target Format

Web Open Font Format

Web Open Font Format (WOFF) is specifically optimized for web use with built-in compression. It's supported by all modern browsers and is ideal for websites. WOFF files are typically 40% smaller than their TTF/OTF equivalents.

Frequently Asked Questions

Common questions about converting DFONT to WOFF

1Why convert DFONT to WOFF?

To use obsolete Mac fonts on the web. DFONT is desktop-only (and Mac-only); WOFF is for web. However, better workflow: DFONT → TTF → WOFF2 (modern web) + WOFF (IE9-11 fallback). This provides optimal compression.

2Can I convert DFONT directly to WOFF?

Most converters require intermediate step: DFONT → TTF → WOFF. DFONT is a Mac desktop format; WOFF is a web format. The TTF intermediate step ensures proper font compilation before web compression.

3Should I convert to WOFF or WOFF2?

WOFF2 for best results. After DFONT → TTF conversion, create both WOFF2 (modern browsers, better compression) and WOFF (IE9-11 fallback). This covers 99.9% of browsers with optimal performance.

4Will the converted WOFF work in all browsers?

WOFF works in IE9+, Chrome, Firefox, Safari, Edge, and all mobile browsers from 2015+. This covers 99%+ of current traffic. For even better compression, also create WOFF2 (25-30% smaller than WOFF).

5Can I use WOFF in desktop applications?

No, WOFF is web-only. For desktop use, keep the intermediate TTF file. For web, use WOFF/WOFF2. Maintain separate files: TTF (desktop), WOFF2 (modern web), WOFF (IE9-11 fallback).

6Does converting DFONT to WOFF preserve font features?

DFONT has no OpenType features to preserve (predates OpenType). The conversion preserves basic glyphs and metrics. After creating TTF, you can add modern features, then those are preserved in WOFF.

7How much smaller is WOFF than DFONT?

WOFF is typically 40-60% smaller due to gzip compression. A 100KB DFONT → 100KB TTF → 40-60KB WOFF. For even better compression, use WOFF2 (60-70% smaller than DFONT/TTF).

8What's the best workflow for DFONT to web fonts?

DFONT → TTF (compilation) → WOFF2 (modern web) + WOFF (IE9-11 fallback). This modernizes obsolete Mac fonts for cross-browser web use with optimal compression. Discard DFONT; keep TTF for desktop use.

Troubleshooting Common Issues

Solutions to problems you might encounter

Conversion requires TTF intermediate step

Most tools can't convert DFONT directly to WOFF. Workflow: DFONT → TTF → WOFF. This is normal. First modernize the DFONT to TTF, then compress to WOFF for web use. Some tools automate this pipeline.

File size increased from DFONT

This seems wrong but may be correct. DFONT has resource fork overhead that's hard to compare. Focus on web delivery: WOFF is typically 40-60% smaller than uncompressed desktop fonts. For even better compression, convert to WOFF2 (60-70% smaller).

Should I use WOFF or WOFF2?

Use both! After DFONT → TTF → WOFF/WOFF2 conversion, provide WOFF2 (modern browsers, best compression) + WOFF (IE9-11 fallback). This covers 99.9% of users with optimal performance.

DFONT had minimal features

DFONT predates OpenType. The converted WOFF has basic glyphs only. This is expected. If you need advanced typography, you'll need to add OpenType features in the intermediate TTF step using font editing software.

Character encoding differs from original

DFONT uses legacy Mac encoding; WOFF uses Unicode. Verify character mapping in the intermediate TTF. Critical characters (currency symbols, accents) may need manual verification to ensure correct Unicode assignment.

When NOT to Use WOFF

Scenarios where you should keep DFONT or choose a different format

Better compression needed
Why not: WOFF2 is 25-30% smaller than WOFF
Use instead: Convert DFONT to WOFF2 instead; use WOFF only as fallback
Modern web only
Why not: If you don't support IE11, WOFF2 is better
Use instead: Convert to WOFF2 from DFONT; skip WOFF unless IE11 needed
Desktop use also needed
Why not: WOFF is web-only; can't use in desktop apps
Use instead: Convert DFONT to TTF (desktop) + WOFF2 (web) separately
