What is AFM?

Adobe Font Metrics (AFM) is a text file describing Type 1 font metrics including character widths, kerning pairs, and bounding boxes.

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 AFM vs PCF?

AFM vs PCF: Key Differences

• •AFM and PCF diverge on compression: lossless compression for the source, lossless compression for the target.
• •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
• •Alpha channel support: PCF lacks transparency support.
• •Storage footprint: Very small, text-based metrics for AFM vs Smaller than BDF for same font for PCF.
• •AFM is optimized for postscript font metrics, pdf font embedding while PCF is designed for x11 system fonts, linux console fonts — choose based on your specific workflow needs

Advantages of AFM

• ✓AFM applies lossless compression specifically calibrated for PostScript font metrics, PDF font embedding.
• ✓AFM enjoys broad native support across operating systems, browsers, and creative tools alike.
• ✓AFM guarantees every bit of the original data survives — no approximations, no shortcuts.
• ✓You will find AFM support built into virtually every tool that handles PostScript font metrics, PDF font embedding — no plugins or converters needed.

Advantages of PCF

• ✓PCF uses lossless compression tailored for X11 system fonts, Linux console fonts.
• ✓PCF is supported natively on virtually every device, browser, and operating system.
• ✓PCF files are bit-for-bit perfect, preserving every pixel and sample for professional work.
• ✓PCF integrates seamlessly with all major creative tools and workflows.

Common Use Cases for AFM to PCF Conversion

• Print design
• Mobile apps
• Desktop publishing
• E-book formatting
• User interfaces
• Marketing materials

Industry Applications

Best Practices for AFM to PCF Conversion

• →Before converting AFM to PCF, review the font license — some licenses restrict format conversion
• →Check hinting data after conversion: PCF may handle TrueType hinting differently than AFM
• →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 AFM to PCF Conversion

• !PCF font doesn't render correctly → check if PCF supports all glyphs present in AFM
• !Licensing restrictions after AFM to PCF conversion → verify the font license allows format conversion
• !Hinting data lost converting AFM 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
