RAF vs ICNS: Key Differences

  • •RAF uses lossless compression while ICNS uses lossless compression — both take the same approach to file size management.
  • •Neither format changes compression philosophy — both are lossless compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
  • •How transparency is handled: ICNS supports transparency, so alpha information is preserved during conversion.
  • •RAF files are typically 20-50MB per photo while ICNS files range 100KB to 5MB for multi-resolution icons
  • •Use case fit: RAF targets fujifilm photography, film simulation processing and ICNS targets macos application icons, retina display icons — your choice depends on which workflow stage you are serving.
