What is DWG?

AutoCAD DWG is the native binary file format for AutoCAD, the industry standard for professional CAD design and drafting.

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 DWG vs FITS?

Use DWG When...

Reach for DWG when your priority is professional cad designs, engineering blueprints — 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.

DWG vs FITS: Key Differences

  • •DWG uses lossless compression while FITS uses lossless compression — both take the same approach to file size management.
  • •Since both DWG and FITS use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
  • •How transparency is handled: FITS supports transparency, so alpha information is preserved during conversion.
  • •Storage footprint: Smaller than DXF due to binary encoding for DWG vs Varies from 1MB to several GB for FITS.
  • •Use case fit: DWG targets professional cad designs, engineering blueprints and FITS targets astronomy, scientific imaging, research — your choice depends on which workflow stage you are serving.

Advantages of DWG

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

Advantages of FITS

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

Best Practices for DWG to FITS Conversion

  • →When converting DWG 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 DWG 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 DWG to FITS Conversion

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