What is PFM?

Printer Font Metrics (PFM) is the binary companion to PFB fonts for Windows, containing font metric data for 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 PFM vs WOFF?

Use PFM When...

Reach for PFM when your priority is windows postscript printing, font pairing — its uncompromising quality ensures every detail is preserved.

Use WOFF When...

Reach for WOFF when your priority is web fonts, responsive web design — its efficient compression makes sharing fast and storage minimal.

PFM vs WOFF: Key Differences

•PFM and WOFF diverge on compression: lossless compression for the source, lossy compression for the target.
•Moving from PFM (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: PFM files typically range Very small, binary format and WOFF files 30-50% smaller than TTF/OTF.
•Use case fit: PFM targets windows postscript printing, font pairing and WOFF targets web fonts, responsive web design — your choice depends on which workflow stage you are serving.

Advantages of PFM

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

Advantages of WOFF

✓WOFF applies lossy compression specifically calibrated for Web fonts, responsive web design.
✓WOFF enjoys broad native support across operating systems, browsers, and creative tools alike.
✓WOFF delivers impressive compression ratios, shrinking files dramatically while keeping visual quality high.
✓You will find WOFF support built into virtually every tool that handles Web fonts, responsive web design — no plugins or converters needed.

Best Practices for PFM to WOFF Conversion

→Converting PFM to WOFF: check that glyph coverage is preserved — some formats have character limitations
→Use WOFF for websites where file size matters
→Test fonts across different browsers and operating systems after conversion
→Always keep a backup of your original files before converting
→Choose the appropriate quality settings for your specific use case

Troubleshooting PFM to WOFF Conversion

!WOFF font doesn't render correctly → check if WOFF supports all glyphs present in PFM
!Licensing restrictions after PFM to WOFF conversion → verify the font license allows format conversion
!Hinting data lost converting PFM to WOFF → some font formats like WOFF may not preserve TrueType hinting
!Special characters missing from converted WOFF → font subsetting may have removed unused glyphs
