What is BMP?

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

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 BMP vs ORF?

Use BMP When...

Reach for BMP when your priority is windows applications, printing, high-quality scanning — 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.

BMP vs ORF: Key Differences

  • •The core technical difference: BMP relies on lossless compression whereas ORF 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.
  • •How transparency is handled: ORF supports transparency, so alpha information is preserved during conversion.
  • •BMP files are typically Very large files due to lack of compression while ORF files range 15-40MB per photo
  • •Use case fit: BMP targets windows applications, printing, high-quality scanning and ORF targets olympus camera raw processing — your choice depends on which workflow stage you are serving.

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.

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.

Troubleshooting BMP to ORF Conversion

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