ORF vs RW2: Key Differences

  • •The core technical difference: ORF relies on lossless compression whereas RW2 uses lossless compression.
  • •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
  • •Alpha channel support: RW2 lacks transparency support.
  • •File sizes: ORF files typically range 15-40MB per photo and RW2 files 20-45MB per photo.
  • •Use case fit: ORF targets olympus camera raw processing and RW2 targets panasonic/lumix camera raw editing — your choice depends on which workflow stage you are serving.

Advantages of ORF

  • ✓ORF compresses data using lossless methods, keeping file sizes manageable for Olympus camera raw processing.
  • ✓Industry-wide support means ORF files open anywhere — from legacy systems to the latest devices.
  • ✓Lossless quality makes ORF the gold standard for archival and master copies.
  • ✓From professional software to open-source alternatives, ORF works out of the box.

Advantages of RW2

  • ✓The lossless nature of RW2 means file sizes stay reasonable while handling Panasonic/Lumix camera raw editing efficiently.
  • ✓From mobile devices to enterprise servers, RW2 is recognized and supported everywhere.
  • ✓The trade-off for RW2's perfection is larger files — but for archival work, it is worth every megabyte.
  • ✓RW2 is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Troubleshooting ORF to RW2 Conversion

  • !RW2 shows visible compression artifacts → lower the compression level or switch to a lossless variant
  • !The converted RW2 image looks washed out → the source ORF likely uses a wider color space than RW2 supports
  • !RW2 file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
  • !Text in the converted RW2 looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
