Troubleshooting JNG to JPG Conversion

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