What is EMF?

Enhanced Metafile (EMF) is an improved Windows vector graphics format with better device independence and color fidelity.

What is ORF?

Olympus Raw Format (ORF) contains raw sensor data from Olympus OM-D, PEN, and other Olympus digital cameras.

When Should You Use EMF vs ORF?

Use EMF When...

Reach for EMF when your priority is office graphics, windows vector rendering — its uncompromising quality ensures every detail is preserved.

Use ORF When...

Reach for ORF when your priority is olympus camera raw processing — its uncompromising quality ensures every detail is preserved.

EMF vs ORF: Key Differences

  • •EMF and ORF 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.
  • •Alpha channel support: ORF lacks transparency support.
  • •Storage footprint: 10KB to 10MB for EMF vs 15-40MB per photo for ORF.
  • •EMF is optimized for office graphics, windows vector rendering while ORF is designed for olympus camera raw processing — choose based on your specific workflow needs

Advantages of EMF

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

Advantages of ORF

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

Best Practices for EMF to ORF Conversion

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

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