Troubleshooting PGM to CRW Conversion

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