TTF vs EOT: Key Differences

  • •TTF and EOT diverge on compression: lossless compression for the source, lossy compression for the target.
  • •Moving from TTF (lossy) to EOT (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
  • •Alpha channel support: EOT lacks transparency support, so semi-transparent pixels from the source will be lost.
  • •Storage footprint: 20KB to 200KB per font for TTF vs Similar to WOFF, 30-50% smaller than TTF for EOT.
  • •Primary audience: TTF is built for desktop publishing, web fonts, documents scenarios, while EOT focuses on legacy ie web fonts, older browser support — pick the format that matches your output requirement.

Troubleshooting TTF to EOT Conversion

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