FITS vs CRW: Key Differences

•The core technical difference: FITS relies on lossless compression whereas CRW 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.
•Alpha channel support: CRW handles transparency.
•CRW files tend to be differently sized than FITS
•Use case fit: FITS targets astronomy, scientific imaging, research and CRW targets legacy canon dslr photography, raw image processing — your choice depends on which workflow stage you are serving.

Advantages of FITS

✓FITS compresses data using lossless methods, keeping file sizes manageable for Astronomy, scientific imaging, research.
✓Industry-wide support means FITS files open anywhere — from legacy systems to the latest devices.
✓Lossless quality makes FITS the gold standard for archival and master copies.
✓From professional software to open-source alternatives, FITS works out of the box.

Advantages of CRW

✓At its core, CRW relies on lossless encoding — a design choice that makes it perfect for Legacy Canon DSLR photography, raw image processing.
✓You won't run into compatibility issues with CRW — it's a universal standard across platforms.
✓File size management with CRW: larger files guaranteed to match the original exactly.
✓Every major application in the Legacy Canon DSLR photography, raw image processing space supports CRW natively.

Best Practices for FITS to CRW Conversion

→When converting FITS to CRW, check whether CRW supports transparency — if not, your transparent areas will be filled with a solid color
→Use CRW for maximum quality archival and FITS for lossless workflows
→Optimize images for web to reduce page load times — tools like our converter let you adjust quality settings before conversion
→Maintain original aspect ratio to avoid distortion during conversion
→Always keep a backup of your original files before converting
→Choose the appropriate quality settings for your specific use case

Troubleshooting FITS to CRW Conversion

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