About ORF
ORF is the raw format Olympus used from its E series DSLRs to its PEN and OM-D mirrorless cameras. When the camera business became OM Digital Solutions in 2021, the new OM System cameras kept it.
Most of these cameras use Four Thirds or Micro Four Thirds sensors, with a 4 by 3 shape, like 5184 by 3888 pixels on the OM-1. An ORF usually holds 12 bits per pixel with lossless compression, and some high resolution shots hold 14.
No browser shows ORF by itself. Filepeek develops it with LibRaw, the open source raw decoder, using the camera's white balance. Show EXIF lists the camera, the lens and the settings, and Export saves a JPEG or PNG.

Questions
Do OM System cameras still save ORF?
Yes. The OM-1, OM-5 and other OM System cameras save ORF like the Olympus models before them, and Filepeek opens both.
Why does it look flatter than on my camera?
Your camera applies its Picture Mode or Art Filter, with extra contrast, color and sharpening, to the photos it shows and saves as JPEG. Filepeek develops the raw data neutrally, with the camera's white balance, so the photo can look flatter here.
How do I convert ORF to JPEG?
Open it here, choose Export, then Save as JPEG. It all happens on your device, so it works as a raw converter that uploads nothing.
Is my photo uploaded?
No. The ORF is developed inside your browser and never leaves your device.
