Troubleshooting CPT to GBR Conversion

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