What is X3F?

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

What is MNG?

Multiple-Image Network Graphics (MNG) is an animation format based on PNG compression, supporting complex frame-based and sprite animations.

When Should You Use X3F vs MNG?

Use X3F When...

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

Use MNG When...

Reach for MNG when your priority is legacy web animation, png-based video clips — its uncompromising quality ensures every detail is preserved.

X3F vs MNG: Key Differences

  • •X3F uses lossless compression while MNG uses lossless compression — both take the same approach to file size management.
  • •Since both X3F and MNG use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
  • •Transparency: Full alpha channel per frame
  • •X3F files are typically 25-60MB per photo while MNG files range Larger than animated GIF
  • •Use case fit: X3F targets sigma/foveon camera raw processing and MNG targets legacy web animation, png-based video clips — your choice depends on which workflow stage you are serving.

Advantages of X3F

  • ✓X3F uses lossless compression tailored for Sigma/Foveon camera raw processing.
  • ✓X3F is supported natively on virtually every device, browser, and operating system.
  • ✓X3F files are bit-for-bit perfect, preserving every pixel and sample for professional work.
  • ✓X3F integrates seamlessly with all major creative tools and workflows.

Advantages of MNG

  • ✓MNG applies lossless compression specifically calibrated for Legacy web animation, PNG-based video clips.
  • ✓MNG enjoys broad native support across operating systems, browsers, and creative tools alike.
  • ✓MNG guarantees every bit of the original data survives — no approximations, no shortcuts.
  • ✓You will find MNG support built into virtually every tool that handles Legacy web animation, PNG-based video clips — no plugins or converters needed.

Best Practices for X3F to MNG Conversion

  • →Before converting X3F to MNG, 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 MNG — you cannot recover detail lost during lossy compression
  • →Check the color profile: X3F images may use a wider gamut than MNG 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 X3F to MNG Conversion

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