FITS vs CR3: Key Differences

•FITS uses lossless compression while CR3 uses lossless compression — both take the same approach to file size management.
•Since both FITS and CR3 use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
•How transparency is handled: CR3 supports transparency, so alpha information is preserved during conversion.
•Storage footprint: Varies from 1MB to several GB for FITS vs varies for CR3.
•Use case fit: FITS targets astronomy, scientific imaging, research and CR3 targets modern canon dslr/mirrorless photography, professional raw editing — your choice depends on which workflow stage you are serving.

Advantages of FITS

✓The lossless nature of FITS means file sizes stay reasonable while handling Astronomy, scientific imaging, research efficiently.
✓From mobile devices to enterprise servers, FITS is recognized and supported everywhere.
✓The trade-off for FITS's perfection is larger files — but for archival work, it is worth every megabyte.
✓FITS is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Advantages of CR3

Troubleshooting FITS to CR3 Conversion

!Converting FITS to CR3 gives blurry output → increase the quality setting before conversion
!Colors look different in CR3 than FITS → check color profile mismatch (sRGB vs Adobe RGB)
!File size changed more than expected → CR3 uses different compression, file size differences of 2-5x are normal
!Transparent areas in FITS turned white in CR3 → CR3 may not support transparency
