Reach for KEY when your priority is apple presentations, slideshows — its efficient compression makes sharing fast and storage minimal.

DCM vs KEY: Key Differences

  • •DCM and KEY diverge on compression: lossless compression for the source, lossy compression for the target.
  • •Moving from DCM (lossy) to KEY (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
  • •How transparency is handled: KEY does not support alpha channels — transparent areas in the source will become opaque.
  • •Storage footprint: 50KB to 500MB per study for DCM vs 5MB to 100MB with media for KEY.
  • •Use case fit: DCM targets medical imaging, radiology, healthcare and KEY targets apple presentations, slideshows — your choice depends on which workflow stage you are serving.

Troubleshooting DCM to KEY Conversion

  • !DCM to KEY formatting looks off → complex layouts with tables and columns may shift between formats
  • !Fonts render differently in KEY → embed fonts or use standard web-safe fonts before converting
  • !Images missing from the KEY output → ensure images are embedded in DCM, not linked externally
  • !Tracked changes disappeared after converting DCM to KEY → some document formats don't support revision tracking
