ICNS vs ORF: Key Differences

  • •ICNS and ORF 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: ORF supports transparency, so alpha information is preserved during conversion.
  • •File sizes: ICNS files typically range 100KB to 5MB for multi-resolution icons and ORF files 15-40MB per photo.
  • •ICNS is optimized for macos application icons, retina display icons while ORF is designed for olympus camera raw processing — choose based on your specific workflow needs
