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 XBM?

X BitMap (XBM) is a monochrome image format that stores pixel data as C source code, commonly used for X11 cursor and icon bitmaps.

When Should You Use FITS vs XBM?

Use FITS When...

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

Use XBM When...

Reach for XBM when your priority is x11 icons, monochrome graphics, embedded ui — its uncompromising quality ensures every detail is preserved.

FITS vs XBM: Key Differences

  • •The core technical difference: FITS relies on lossless compression whereas XBM 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.
  • •Alpha channel support: XBM lacks transparency support.
  • •File sizes: FITS files typically range Varies from 1MB to several GB and XBM files Very small, minimal overhead.
  • •FITS is optimized for astronomy, scientific imaging, research while XBM is designed for x11 icons, monochrome graphics, embedded ui — choose based on your specific workflow needs

Advantages of FITS

  • ✓FITS compresses data using lossless methods, keeping file sizes manageable for Astronomy, scientific imaging, research.
  • ✓Industry-wide support means FITS files open anywhere — from legacy systems to the latest devices.
  • ✓Lossless quality makes FITS the gold standard for archival and master copies.
  • ✓From professional software to open-source alternatives, FITS works out of the box.

Advantages of XBM

  • ✓XBM compresses data using lossless methods, keeping file sizes manageable for X11 icons, monochrome graphics, embedded UI.
  • ✓Industry-wide support means XBM files open anywhere — from legacy systems to the latest devices.
  • ✓Lossless quality makes XBM the gold standard for archival and master copies.
  • ✓From professional software to open-source alternatives, XBM works out of the box.

Best Practices for FITS to XBM Conversion

  • →When converting FITS to XBM, check whether XBM supports transparency — if not, your transparent areas will be filled with a solid color
  • →Use XBM 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 XBM Conversion

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