What is MNG?

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

What is FITS?

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

When Should You Use MNG vs FITS?

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.

Use FITS When...

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

MNG vs FITS: Key Differences

  • •The core technical difference: MNG 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.
  • •How transparency is handled: FITS supports transparency, so alpha information is preserved during conversion.
  • •MNG files are typically Larger than animated GIF while FITS files range Varies from 1MB to several GB
  • •Primary audience: MNG is built for legacy web animation, png-based video clips scenarios, while FITS focuses on astronomy, scientific imaging, research — pick the format that matches your output requirement.

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.
  • ✓MNG is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Troubleshooting MNG to FITS Conversion

  • !Converting MNG to FITS gives blurry output → increase the quality setting before conversion
  • !Colors look different in FITS than MNG → 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 MNG turned white in FITS → FITS may not support transparency
