When Should You Use PFA vs WOFF?

PFA vs WOFF: Key Differences

• •The core technical difference: PFA relies on lossless compression whereas WOFF uses lossy compression.
• •Moving from PFA (lossy) to WOFF (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
• •How transparency is handled: WOFF does not support alpha channels — transparent areas in the source will become opaque.
• •File sizes: PFA files typically range 20-100KB per font and WOFF files 30-50% smaller than TTF/OTF.
• •PFA is optimized for professional printing, postscript devices while WOFF is designed for web fonts, responsive web design — choose based on your specific workflow needs
