What is X3F?

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

What is PICT?

Macintosh PICT is a legacy vector and raster image format used by classic Mac OS applications for illustrations and graphics.

When Should You Use X3F vs PICT?

Use X3F When...

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

Use PICT When...

Reach for PICT when your priority is classic mac graphics, legacy desktop publishing — its uncompromising quality ensures every detail is preserved.

X3F vs PICT: Key Differences

  • •X3F and PICT diverge on compression: lossless compression for the source, lossless compression for the target.
  • •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
  • •How transparency is handled: PICT supports transparency, so alpha information is preserved during conversion.
  • •File sizes: X3F files typically range 25-60MB per photo and PICT files Varies widely by content complexity.
  • •Use case fit: X3F targets sigma/foveon camera raw processing and PICT targets classic mac graphics, legacy desktop publishing — your choice depends on which workflow stage you are serving.

Advantages of X3F

  • ✓X3F applies lossless compression specifically calibrated for Sigma/Foveon camera raw processing.
  • ✓X3F enjoys broad native support across operating systems, browsers, and creative tools alike.
  • ✓X3F guarantees every bit of the original data survives — no approximations, no shortcuts.
  • ✓You will find X3F support built into virtually every tool that handles Sigma/Foveon camera raw processing — no plugins or converters needed.

Advantages of PICT

  • ✓PICT uses lossless compression tailored for Classic Mac graphics, legacy desktop publishing.
  • ✓PICT is supported natively on virtually every device, browser, and operating system.
  • ✓PICT files are bit-for-bit perfect, preserving every pixel and sample for professional work.
  • ✓PICT integrates seamlessly with all major creative tools and workflows.

Troubleshooting X3F to PICT Conversion

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