EML vs HTML: Key Differences

  • •Moving from EML (lossy) to HTML (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
  • •How transparency is handled: HTML does not support alpha channels — transparent areas in the source will become opaque.
  • •File sizes: EML files typically range Small for plain text, larger with attachments and HTML files 10KB to 500KB.
  • •Use case fit: EML targets email export, message archiving, mail migration and HTML targets web pages, documentation — your choice depends on which workflow stage you are serving.

  • ✓Every major application in the Email export, message archiving, mail migration space supports EML natively.

Advantages of HTML

  • ✓The lossy nature of HTML means file sizes stay reasonable while handling Web pages, documentation efficiently.
  • ✓From mobile devices to enterprise servers, HTML is recognized and supported everywhere.
