MAC vs GBR: Key Differences

•MAC and GBR diverge on compression: lossless compression for the source, lossless compression for the target.
•Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
•How transparency is handled: GBR supports transparency, so alpha information is preserved during conversion.
•Storage footprint: Very small, fixed 576x720 size for MAC vs Very small, typically under 100KB for GBR.
•Primary audience: MAC is built for legacy mac graphics, vintage bitmap art scenarios, while GBR focuses on digital painting, gimp brush presets — pick the format that matches your output requirement.

Troubleshooting MAC 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 MAC 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
