What is PFB?

PostScript Type 1 Binary (PFB) is a compact binary printer font format, more efficient than ASCII PFA for professional printing.

What is WOFF?

WOFF (Web Open Font Format) is a font format specifically designed for use on the web, compressing TrueType or OpenType fonts for faster loading.

When Should You Use PFB vs WOFF?

PFB vs WOFF: Key Differences

• •PFB uses lossless compression while WOFF uses lossy compression — this is the fundamental technical difference between the two formats.
• •The switch from lossless compression to lossy compression means you gain significant space savings while accepting minor quality trade-offs.
• •Alpha channel support: WOFF lacks transparency support, so semi-transparent pixels from the source will be lost.
• •Storage footprint: 15-80KB per font, smaller than PFA for PFB vs 30-50% smaller than TTF/OTF for WOFF.
• •PFB is optimized for professional printing, legacy typesetting while WOFF is designed for web fonts, responsive web design — choose based on your specific workflow needs
