Troubleshooting RW2 to PNG Conversion

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