Troubleshooting BPG 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 BPG 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
