What is BMP?

BMP (Bitmap Image File) is a raster graphics format created by Microsoft for Windows compatibility.

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 BMP vs FITS?

Use BMP When...

Reach for BMP when your priority is windows applications, printing, high-quality scanning — 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.

BMP vs FITS: Key Differences

  • •BMP uses lossless compression while FITS uses lossless compression — both take the same approach to file size management.
  • •Since both BMP and FITS use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
  • •Alpha channel support: FITS lacks transparency support.
  • •Storage footprint: Very large files due to lack of compression for BMP vs Varies from 1MB to several GB for FITS.
  • •BMP is optimized for windows applications, printing, high-quality scanning while FITS is designed for astronomy, scientific imaging, research — choose based on your specific workflow needs

Advantages of BMP

  • ✓The lossless nature of BMP means file sizes stay reasonable while handling Windows applications, printing, high-quality scanning efficiently.
  • ✓From mobile devices to enterprise servers, BMP is recognized and supported everywhere.
  • ✓The trade-off for BMP's perfection is larger files — but for archival work, it is worth every megabyte.
  • ✓BMP is a first-class citizen in all major software ecosystems, from creative suites to development environments.

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 BMP to FITS Conversion

  • →When converting BMP to FITS, check whether FITS supports transparency — if not, your transparent areas will be filled with a solid color
  • →Use FITS for maximum quality archival and BMP 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 BMP to FITS Conversion

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