What is PCF?

Portable Compiled Format (PCF) is the compiled binary version of BDF bitmap fonts for efficient X11 font rendering.

When Should You Use PFB vs PCF?

PFB vs PCF: Key Differences

• •PFB and PCF diverge on compression: lossless compression for the source, lossless compression for the target.
• •Since both PFB and PCF use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
• •Alpha channel support: PCF lacks transparency support.
• •PFB files are typically 15-80KB per font, smaller than PFA while PCF files range Smaller than BDF for same font
• •Use case fit: PFB targets professional printing, legacy typesetting and PCF targets x11 system fonts, linux console fonts — your choice depends on which workflow stage you are serving.

Advantages of PFB

• ✓PFB applies lossless compression specifically calibrated for Professional printing, legacy typesetting.
• ✓PFB enjoys broad native support across operating systems, browsers, and creative tools alike.

• ✓You will find PFB support built into virtually every tool that handles Professional printing, legacy typesetting — no plugins or converters needed.

Advantages of PCF

• ✓At its core, PCF relies on lossless encoding — a design choice that makes it perfect for X11 system fonts, Linux console fonts.
• ✓You won't run into compatibility issues with PCF — it's a universal standard across platforms.
• ✓File size management with PCF: larger files guaranteed to match the original exactly.

Industry Applications

Best Practices for PFB to PCF Conversion

• →Before converting PFB to PCF, review the font license — some licenses restrict format conversion
• →Check hinting data after conversion: PCF may handle TrueType hinting differently than PFB
• →Verify that all character sets (Latin, Cyrillic, CJK, etc.) survived the conversion intact
• →Test the converted font in both a browser and a desktop application
• →Keep the original font file in case the conversion alters spacing metrics

Troubleshooting PFB to PCF Conversion

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