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 SVG?

SVG (Scalable Vector Graphics) is an XML-based vector image format that defines images as mathematical paths, allowing infinite scalability without quality loss.

When Should You Use FITS vs SVG?

Use FITS When...

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

Use SVG When...

Reach for SVG when your priority is icons, logos, illustrations, responsive web graphics — its uncompromising quality ensures every detail is preserved.

FITS vs SVG: Key Differences

  • •The core technical difference: FITS relies on lossless compression whereas SVG 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: SVG supports transparency, so alpha information is preserved during conversion.
  • •FITS files are typically Varies from 1MB to several GB while SVG files range 1KB to 100KB depending on complexity
  • •Use case fit: FITS targets astronomy, scientific imaging, research and SVG targets icons, logos, illustrations, responsive web graphics — your choice depends on which workflow stage you are serving.

Advantages of FITS

  • ✓FITS applies lossless compression specifically calibrated for Astronomy, scientific imaging, research.
  • ✓FITS enjoys broad native support across operating systems, browsers, and creative tools alike.
  • ✓FITS guarantees every bit of the original data survives — no approximations, no shortcuts.
  • ✓You will find FITS support built into virtually every tool that handles Astronomy, scientific imaging, research — no plugins or converters needed.

Best Practices for FITS to SVG Conversion

  • →When converting FITS to SVG, check whether SVG supports transparency — if not, your transparent areas will be filled with a solid color
  • →Use SVG for maximum quality archival and FITS for lossless workflows
  • →Optimize images for web to reduce page load times — tools like our converter let you adjust quality settings before conversion
  • →Maintain original aspect ratio to avoid distortion during conversion
  • →Always keep a backup of your original files before converting
  • →Choose the appropriate quality settings for your specific use case

Troubleshooting FITS to SVG Conversion

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