When Should You Use CFF vs TTF?

CFF vs TTF: Key Differences

• •CFF uses lossless compression while TTF uses lossless compression — both take the same approach to file size management.
• •Since both CFF and TTF use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
• •How transparency is handled: TTF supports transparency, so alpha information is preserved during conversion.
• •CFF files are typically 15-100KB per font while TTF files range 20KB to 200KB per font
• •Use case fit: CFF targets professional printing, pdf fonts and TTF targets desktop publishing, web fonts, documents — your choice depends on which workflow stage you are serving.

• ✓The lossless nature of CFF means file sizes stay reasonable while handling Professional printing, PDF fonts efficiently.
• ✓From mobile devices to enterprise servers, CFF is recognized and supported everywhere.
• ✓The trade-off for CFF's perfection is larger files — but for archival work, it is worth every megabyte.
• ✓CFF is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Industry Applications

Best Practices for CFF to TTF Conversion

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

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