Reach for FITS when your priority is astronomy, scientific imaging, research — its uncompromising quality ensures every detail is preserved.

PICT vs FITS: Key Differences

  • •PICT uses lossless compression while FITS uses lossless compression — both take the same approach to file size management.
  • •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: FITS lacks transparency support.
  • •Storage footprint: Varies widely by content complexity for PICT vs Varies from 1MB to several GB for FITS.
  • •PICT is optimized for classic mac graphics, legacy desktop publishing while FITS is designed for astronomy, scientific imaging, research — choose based on your specific workflow needs

Advantages of PICT

  • ✓At its core, PICT relies on lossless encoding — a design choice that makes it perfect for Classic Mac graphics, legacy desktop publishing.
  • ✓You won't run into compatibility issues with PICT — it's a universal standard across platforms.
  • ✓File size management with PICT: larger files guaranteed to match the original exactly.
  • ✓Every major application in the Classic Mac graphics, legacy desktop publishing space supports PICT natively.

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.

Troubleshooting PICT to FITS Conversion

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