What is FITS?

Flexible Image Transport System (FITS) is a scientific data format used primarily in astronomy for storing and transmitting images and datasets.

What is CDR?

CorelDRAW (CDR) is the native vector graphics format for CorelDRAW, popular in professional design and signage.

When Should You Use FITS vs CDR?

Use FITS When...

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

Use CDR When...

Reach for CDR when your priority is vector design, coreldraw projects — its uncompromising quality ensures every detail is preserved.

FITS vs CDR: Key Differences

  • •The core technical difference: FITS relies on lossless compression whereas CDR 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: Supports vector transparency
  • •FITS files are typically Varies from 1MB to several GB while CDR files range 500KB to 30MB
  • •Primary audience: FITS is built for astronomy, scientific imaging, research scenarios, while CDR focuses on vector design, coreldraw projects — pick the format that matches your output requirement.

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 CDR

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

Troubleshooting FITS to CDR Conversion

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