What is a .ORF file?
Everything worth knowing about Olympus Raw Format (Olympus/OM System camera raw image).
An ORF file is a raw image from an Olympus or OM System camera, the unprocessed sensor data, like a digital negative. On Windows, install the free Raw Image Extension (Microsoft Store) to see thumbnails; use the free OM Workspace to edit. To share, convert to JPG; to archive, convert to DNG. Olympus Viewer and Olympus Master are discontinued; use OM Workspace instead.

Frequently asked questions
Is my .ORF file uploaded?
No. The viewer reads your .ORF file. RAW files are big and personal, so they never leave your device.
Is this the real RAW image?
It's the full-size JPEG preview the camera stored inside the RAW file, which is what the camera displays. It has the camera's own colors and white balance. Developing the raw sensor data with your own settings is coming soon.
Why is the preview small for my camera?
Some older cameras (and Sigma, Kodak and Minolta models) only embed a small thumbnail. The panel tells you the preview size and how it compares to the sensor.
Where does the location come from?
From the GPS data your camera or phone saved in the file. If you share the photo, remember this data travels with the original RAW.
Can I convert RAW to JPG here?
Yes: open the file and use Save as JPG. You'll get the camera's preview in full quality. For edited exports with your own exposure and color, use a RAW editor until our developer arrives.
