What is PNG?

PNG (Portable Network Graphics) is a raster graphics file format that supports lossless data compression. PNG was created as an improved, non-patented replacement for GIF.

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 PNG vs ORF?

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

PNG vs ORF: Key Differences

  • •The core technical difference: PNG 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.
  • •Alpha channel support: ORF lacks transparency support.
  • •File sizes: PNG files typically range 20KB to several MB and ORF files 15-40MB per photo.
  • •Use case fit: PNG targets graphics, logos, images requiring transparency and ORF targets olympus camera raw processing — your choice depends on which workflow stage you are serving.

Advantages of PNG

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

Advantages of ORF

  • ✓The lossless nature of ORF means file sizes stay reasonable while handling Olympus camera raw processing efficiently.
  • ✓From mobile devices to enterprise servers, ORF is recognized and supported everywhere.
  • ✓The trade-off for ORF's perfection is larger files — but for archival work, it is worth every megabyte.
  • ✓ORF is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Troubleshooting PNG 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 PNG 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
