What is EPS?

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

What is X3F?

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

When Should You Use EPS vs X3F?

Use EPS When...

Reach for EPS when your priority is professional printing, vector illustration — 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.

EPS vs X3F: Key Differences

  • •The core technical difference: EPS 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.
  • •Alpha channel support: X3F lacks transparency support.
  • •Storage footprint: 100KB to 10MB for EPS vs 25-60MB per photo for X3F.
  • •Use case fit: EPS targets professional printing, vector illustration and X3F targets sigma/foveon camera raw processing — your choice depends on which workflow stage you are serving.

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.

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.

Common Use Cases for EPS to X3F Conversion

Best Practices for EPS to X3F Conversion

  • →Before converting EPS 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: EPS 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 EPS to X3F Conversion

  • !Converting EPS to X3F gives blurry output → increase the quality setting before conversion
  • !Colors look different in X3F than EPS → 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 EPS turned white in X3F → X3F may not support transparency
