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 TTF?

TTF (TrueType Font) is a font format developed by Apple and Microsoft, widely used on both Windows and macOS for high-quality text rendering.

When Should You Use PFB vs TTF?

PFB vs TTF: Key Differences

• •The core technical difference: PFB relies on lossless compression whereas TTF uses lossless compression.
• •Neither format changes compression philosophy — both are lossless compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
• •Alpha channel support: TTF lacks transparency support.
• •File sizes: PFB files typically range 15-80KB per font, smaller than PFA and TTF files 20KB to 200KB per font.
• •Use case fit: PFB targets professional printing, legacy typesetting and TTF targets desktop publishing, web fonts, documents — your choice depends on which workflow stage you are serving.

Advantages of PFB

• ✓At its core, PFB relies on lossless encoding — a design choice that makes it perfect for Professional printing, legacy typesetting.
• ✓You won't run into compatibility issues with PFB — it's a universal standard across platforms.
• ✓File size management with PFB: larger files guaranteed to match the original exactly.
• ✓Every major application in the Professional printing, legacy typesetting space supports PFB natively.

Advantages of TTF

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