When Should You Use TTF vs DFONT?

TTF vs DFONT: Key Differences

• •TTF and DFONT diverge on compression: lossless compression for the source, lossless compression for the target.
• •Since both TTF and DFONT use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
• •Transparency: N/A
• •File sizes: TTF files typically range 20KB to 200KB per font and DFONT files 20-200KB per font.
• •Primary audience: TTF is built for desktop publishing, web fonts, documents scenarios, while DFONT focuses on legacy mac system fonts, classic macos — pick the format that matches your output requirement.
