PPSM vs ICS: Key Differences

  • •PPSM and ICS diverge on compression: lossless compression for the source, lossless compression for the target.
  • •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
  • •How transparency is handled: ICS supports transparency, so alpha information is preserved during conversion.
  • •File sizes: PPSM files typically range N/A and ICS files Very small per event.
  • •PPSM is optimized for interactive kiosks, automated presentations with macros while ICS is designed for calendar sharing, event scheduling, meeting exports — choose based on your specific workflow needs
