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 WOFF2?

WOFF2 (Web Open Font Format 2) is the next-generation webfont format with significantly better compression than WOFF, reducing font download sizes by 30-50%.

When Should You Use TTC vs WOFF2?

TTC vs WOFF2: Key Differences

• •The core technical difference: TTC relies on lossless compression whereas WOFF2 uses lossy compression.
• •Moving from TTC (lossy) to WOFF2 (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
• •Alpha channel support: WOFF2 lacks transparency support, so semi-transparent pixels from the source will be lost.
• •TTC files are typically 5-30MB for CJK font collections while WOFF2 files range 50% smaller than WOFF, 70% smaller than TTF
• •TTC is optimized for font distribution, cjk font collections while WOFF2 is designed for modern web fonts, optimized performance — choose based on your specific workflow needs
