What is TTC?

TrueType Collection (TTC) bundles multiple TrueType fonts into a single file, commonly used for CJK (Chinese, Japanese, Korean) font families.

What is DFONT?

Mac Data Fork Font (DFONT) is a legacy macOS font format that stores font data in the resource fork of classic Mac OS files.

When Should You Use TTC vs DFONT?

TTC vs DFONT: Key Differences

• •The core technical difference: TTC relies on lossless compression whereas DFONT uses lossless compression.
• •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
• •Transparency: N/A
• •TTC files are typically 5-30MB for CJK font collections while DFONT files range 20-200KB per font
• •Use case fit: TTC targets font distribution, cjk font collections and DFONT targets legacy mac system fonts, classic macos — your choice depends on which workflow stage you are serving.

Advantages of TTC

• ✓TTC uses lossless compression tailored for Font distribution, CJK font collections.
• ✓TTC is supported natively on virtually every device, browser, and operating system.
• ✓TTC files are bit-for-bit perfect, preserving every pixel and sample for professional work.
• ✓TTC integrates seamlessly with all major creative tools and workflows.

Advantages of DFONT

• ✓The lossless nature of DFONT means file sizes stay reasonable while handling Legacy Mac system fonts, classic macOS efficiently.
• ✓From mobile devices to enterprise servers, DFONT is recognized and supported everywhere.
• ✓The trade-off for DFONT's perfection is larger files — but for archival work, it is worth every megabyte.
• ✓DFONT is a first-class citizen in all major software ecosystems, from creative suites to development environments.
