When Should You Use FON vs BDF?

Use FON When...

Reach for FON when your priority is windows system fonts, ui font resources — its uncompromising quality ensures every detail is preserved.

Use BDF When...

Reach for BDF when your priority is x11 terminal fonts, embedded system displays — its uncompromising quality ensures every detail is preserved.

FON vs BDF: Key Differences

•FON and BDF 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.
•How transparency is handled: BDF supports transparency, so alpha information is preserved during conversion.
•Storage footprint: Small system font resources for FON vs Moderate, plain text font data for BDF.
•Primary audience: FON is built for windows system fonts, ui font resources scenarios, while BDF focuses on x11 terminal fonts, embedded system displays — pick the format that matches your output requirement.

Best Practices for FON to BDF Conversion

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

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