What is APNG?

Animated PNG (APNG) extends the PNG format with frame-based animation support while maintaining full backward compatibility with standard PNG decoders.

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 APNG vs FITS?

Use APNG When...

Reach for APNG when your priority is web animations, game sprites, animated icons — 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.

APNG vs FITS: Key Differences

  • •The core technical difference: APNG relies on lossless compression whereas FITS uses lossless compression.
  • •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
  • •How transparency is handled: FITS supports transparency, so alpha information is preserved during conversion.
  • •APNG files are typically Larger than GIF but better quality while FITS files range Varies from 1MB to several GB
  • •Primary audience: APNG is built for web animations, game sprites, animated icons scenarios, while FITS focuses on astronomy, scientific imaging, research — pick the format that matches your output requirement.

Advantages of APNG

  • ✓APNG uses lossless compression tailored for Web animations, game sprites, animated icons.
  • ✓APNG is supported natively on virtually every device, browser, and operating system.
  • ✓APNG files are bit-for-bit perfect, preserving every pixel and sample for professional work.
  • ✓APNG integrates seamlessly with all major creative tools and workflows.

Troubleshooting APNG to FITS Conversion

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