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 PFM?

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

When Should You Use AFM vs PFM?

Use AFM When...

Reach for AFM when your priority is postscript font metrics, pdf font embedding — its uncompromising quality ensures every detail is preserved.

Use PFM When...

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

AFM vs PFM: Key Differences

•The core technical difference: AFM relies on lossless compression whereas PFM uses lossless compression.
•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: PFM lacks transparency support.
•Storage footprint: Very small, text-based metrics for AFM vs Very small, binary format for PFM.
•Use case fit: AFM targets postscript font metrics, pdf font embedding and PFM targets windows postscript printing, font pairing — your choice depends on which workflow stage you are serving.

Best Practices for AFM to PFM Conversion

→Before converting AFM to PFM, review the font license — some licenses restrict format conversion
→Check hinting data after conversion: PFM 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 PFM Conversion

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