When Should You Use WOFF2 vs PFB?

WOFF2 vs PFB: Key Differences

• •The core technical difference: WOFF2 relies on lossy compression whereas PFB uses lossless compression.
• •Converting from WOFF2 to PFB changes compression type: lossless source becomes larger but with full quality preservation.
• •How transparency is handled: PFB supports transparency, so alpha information is preserved during conversion.
• •WOFF2 files are typically 50% smaller than WOFF, 70% smaller than TTF while PFB files range 15-80KB per font, smaller than PFA
• •Primary audience: WOFF2 is built for modern web fonts, optimized performance scenarios, while PFB focuses on professional printing, legacy typesetting — pick the format that matches your output requirement.
