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 MNG?

Multiple-Image Network Graphics (MNG) is an animation format based on PNG compression, supporting complex frame-based and sprite animations.

When Should You Use FITS vs MNG?

Use FITS When...

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

Use MNG When...

Reach for MNG when your priority is legacy web animation, png-based video clips — its uncompromising quality ensures every detail is preserved.

FITS vs MNG: Key Differences

  • •The core technical difference: FITS relies on lossless compression whereas MNG 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: Full alpha channel per frame
  • •FITS files are typically Varies from 1MB to several GB while MNG files range Larger than animated GIF
  • •Use case fit: FITS targets astronomy, scientific imaging, research and MNG targets legacy web animation, png-based video clips — 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 MNG

  • ✓The lossless nature of MNG means file sizes stay reasonable while handling Legacy web animation, PNG-based video clips efficiently.
  • ✓From mobile devices to enterprise servers, MNG is recognized and supported everywhere.
  • ✓The trade-off for MNG's perfection is larger files — but for archival work, it is worth every megabyte.

Troubleshooting FITS to MNG Conversion

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