CPT vs FITS: Key Differences

  • •The core technical difference: CPT relies on lossless compression whereas FITS 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: N/A - Scientific data format
  • •CPT files are typically Large due to layer data while FITS files range Varies from 1MB to several GB
  • •CPT is optimized for corel image editing, photo manipulation while FITS is designed for astronomy, scientific imaging, research — choose based on your specific workflow needs

Advantages of CPT
