About JNG and MAC

JNG

JNG (JNG images) - JPEG Network Graphics, JPEG-based lossy animation format. Best for legacy web animation, lossy image sequences.

MAC

MAC (MacPaint MAC) - MacPaint Bitmap, classic Mac paint program image format. Ideal for legacy mac graphics, vintage bitmap art.

Troubleshooting JNG to MAC Conversion

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