When Should You Use CFF vs PFA?

CFF vs PFA: Key Differences

• •CFF and PFA 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: PFA supports transparency, so alpha information is preserved during conversion.
• •Storage footprint: 15-100KB per font for CFF vs 20-100KB per font for PFA.
• •Primary audience: CFF is built for professional printing, pdf fonts scenarios, while PFA focuses on professional printing, postscript devices — pick the format that matches your output requirement.

Industry Applications

Best Practices for CFF to PFA Conversion

• →Converting CFF to PFA: check that glyph coverage is preserved — some formats have character limitations
• →Use PFA for cross-platform compatibility
• →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 CFF to PFA Conversion

• !The converted PFA font has incorrect metrics → advance width and kerning values may differ between formats despite identical glyphs
• !PFA file looks heavier or lighter than CFF → font rendering engines handle weight and anti-aliasing differently per format
• !OpenType features (ligatures, swashes) lost after conversion to PFA → verify the target format supports advanced typographic features
• !Variable font axes missing from the converted PFA → variable font support varies significantly between formats
