What is ORF?

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

What is BMP?

BMP (Bitmap Image File) is a raster graphics format created by Microsoft for Windows compatibility.

When Should You Use ORF vs BMP?

Use ORF When...

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

Use BMP When...

Reach for BMP when your priority is windows applications, printing, high-quality scanning — its uncompromising quality ensures every detail is preserved.

ORF vs BMP: Key Differences

  • •ORF and BMP 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: BMP lacks transparency support.
  • •Storage footprint: 15-40MB per photo for ORF vs Very large files due to lack of compression for BMP.
  • •Use case fit: ORF targets olympus camera raw processing and BMP targets windows applications, printing, high-quality scanning — your choice depends on which workflow stage you are serving.

Advantages of ORF

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

Advantages of BMP

  • ✓BMP compresses data using lossless methods, keeping file sizes manageable for Windows applications, printing, high-quality scanning.
  • ✓Industry-wide support means BMP files open anywhere — from legacy systems to the latest devices.
  • ✓Lossless quality makes BMP the gold standard for archival and master copies.
  • ✓From professional software to open-source alternatives, BMP works out of the box.

Best Practices for ORF to BMP Conversion

  • →When converting ORF to BMP, check whether BMP supports transparency — if not, your transparent areas will be filled with a solid color
  • →Use BMP for maximum quality archival and ORF for lossless workflows
  • →Optimize images for web to reduce page load times — tools like our converter let you adjust quality settings before conversion
  • →Maintain original aspect ratio to avoid distortion during conversion
  • →Always keep a backup of your original files before converting
  • →Choose the appropriate quality settings for your specific use case

Troubleshooting ORF to BMP Conversion

  • !BMP shows visible compression artifacts → lower the compression level or switch to a lossless variant
  • !The converted BMP image looks washed out → the source ORF likely uses a wider color space than BMP supports
  • !BMP file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
  • !Text in the converted BMP looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
