What is DXF?

AutoCAD DXF (Drawing Exchange Format) is an open CAD vector format for interoperable exchange between CAD applications.

What is X3F?

Sigma Raw (X3F) contains raw sensor data from Sigma cameras using the unique Foveon X3 sensor technology.

When Should You Use DXF vs X3F?

Use DXF When...

Reach for DXF when your priority is cad file exchange, architectural drawings — its uncompromising quality ensures every detail is preserved.

Use X3F When...

Reach for X3F when your priority is sigma/foveon camera raw processing — its uncompromising quality ensures every detail is preserved.

DXF vs X3F: Key Differences

  • •The core technical difference: DXF relies on lossless compression whereas X3F 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: X3F supports transparency, so alpha information is preserved during conversion.
  • •DXF files are typically Varies by design complexity while X3F files range 25-60MB per photo
  • •Use case fit: DXF targets cad file exchange, architectural drawings and X3F targets sigma/foveon camera raw processing — your choice depends on which workflow stage you are serving.

Advantages of DXF

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

Best Practices for DXF to X3F Conversion

  • →Before converting DXF to X3F, decide whether you need maximum quality or smallest file size — this determines which format truly fits
  • →Save a master copy in a lossless format before converting to X3F — you cannot recover detail lost during lossy compression
  • →Check the color profile: DXF images may use a wider gamut than X3F supports, causing a visible shift after conversion
  • →Resize images to the final display dimensions before converting — this avoids unnecessary processing of oversized files
  • →Run a single test conversion first to verify quality meets your standards
  • →Strip unnecessary metadata to reduce file size after conversion

Troubleshooting DXF to X3F Conversion

  • !Converting DXF to X3F gives blurry output → increase the quality setting before conversion
  • !Colors look different in X3F than DXF → check color profile mismatch (sRGB vs Adobe RGB)
  • !File size changed more than expected → X3F uses different compression, file size differences of 2-5x are normal
  • !Transparent areas in DXF turned white in X3F → X3F may not support transparency
