RAF vs ORF: Key Differences

  • •RAF 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.
  • •Transparency: N/A
  • •Storage footprint: 20-50MB per photo for RAF vs 15-40MB per photo for ORF.
  • •Use case fit: RAF targets fujifilm photography, film simulation processing and ORF targets olympus camera raw processing — your choice depends on which workflow stage you are serving.

Advantages of RAF

  • ✓RAF applies lossless compression specifically calibrated for Fujifilm photography, film simulation processing.
  • ✓RAF enjoys broad native support across operating systems, browsers, and creative tools alike.
  • ✓RAF guarantees every bit of the original data survives — no approximations, no shortcuts.
  • ✓You will find RAF support built into virtually every tool that handles Fujifilm photography, film simulation processing — no plugins or converters needed.

Advantages of ORF

  • ✓ORF uses lossless compression tailored for Olympus camera raw processing.
  • ✓ORF is supported natively on virtually every device, browser, and operating system.
  • ✓ORF files are bit-for-bit perfect, preserving every pixel and sample for professional work.
  • ✓ORF integrates seamlessly with all major creative tools and workflows.

Troubleshooting RAF to ORF Conversion

  • !ORF shows visible compression artifacts → lower the compression level or switch to a lossless variant
  • !The converted ORF image looks washed out → the source RAF likely uses a wider color space than ORF supports
  • !ORF file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
  • !Text in the converted ORF looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
