  • !GBR shows visible compression artifacts → lower the compression level or switch to a lossless variant
  • !The converted GBR image looks washed out → the source PEF likely uses a wider color space than GBR supports

  • !Text in the converted GBR looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
