What is X3F?

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

What is EPS?

Encapsulated PostScript (EPS) is a vector graphics format used for high-quality printing and professional design workflows.

When Should You Use X3F vs EPS?

Use X3F When...

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

Use EPS When...

Reach for EPS when your priority is professional printing, vector illustration — its uncompromising quality ensures every detail is preserved.

X3F vs EPS: Key Differences

  • •X3F uses lossless compression while EPS uses lossless compression — both take the same approach to file size management.
  • •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: EPS supports transparency, so alpha information is preserved during conversion.
  • •File sizes: X3F files typically range 25-60MB per photo and EPS files 100KB to 10MB.
  • •Use case fit: X3F targets sigma/foveon camera raw processing and EPS targets professional printing, vector illustration — your choice depends on which workflow stage you are serving.

Advantages of X3F

  • ✓At its core, X3F relies on lossless encoding — a design choice that makes it perfect for Sigma/Foveon camera raw processing.
  • ✓You won't run into compatibility issues with X3F — it's a universal standard across platforms.
  • ✓File size management with X3F: larger files guaranteed to match the original exactly.
  • ✓Every major application in the Sigma/Foveon camera raw processing space supports X3F natively.

Advantages of EPS

  • ✓EPS uses lossless compression tailored for Professional printing, vector illustration.
  • ✓EPS is supported natively on virtually every device, browser, and operating system.
  • ✓EPS files are bit-for-bit perfect, preserving every pixel and sample for professional work.
  • ✓EPS integrates seamlessly with all major creative tools and workflows.

Common Use Cases for X3F to EPS Conversion

Best Practices for X3F to EPS Conversion

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

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