FITS vs GBR: Key Differences

•The core technical difference: FITS relies on lossless compression whereas GBR uses lossless compression.
•Neither format changes compression philosophy — both are lossless compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
•Transparency: Grayscale alpha for brush opacity
•FITS files are typically Varies from 1MB to several GB while GBR files range Very small, typically under 100KB
•Use case fit: FITS targets astronomy, scientific imaging, research and GBR targets digital painting, gimp brush presets — your choice depends on which workflow stage you are serving.

Troubleshooting FITS to GBR Conversion

!Converting FITS to GBR gives blurry output → increase the quality setting before conversion
!Colors look different in GBR than FITS → check color profile mismatch (sRGB vs Adobe RGB)
!File size changed more than expected → GBR uses different compression, file size differences of 2-5x are normal
!Transparent areas in FITS turned white in GBR → GBR may not support transparency
