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