A 3FR file is a RAW image format created by Hasselblad, a world-class manufacturer of professional medium-format cameras.
Unlike compressed formats such as JPG, a 3FR file preserves full sensor data, dynamic range, color depth, and every detail captured by the camera.
This makes 3FR ideal for high-end photography, studio work, and advanced post-production editing.
Because RAW files are very large, photographers often convert or compress them for faster sharing, storing, or editing.
With OctoConvert, you can easily convert 3FR files into more common formats like JPG, PNG, TIFF, WebP, or DNG without losing essential quality
3FR files cannot be opened by every basic image viewer because they contain unprocessed RAW data.
However, they are fully supported by most professional image-editing software.
You can open 3FR files using:
Hasselblad Phocus (Official Software)
Adobe Lightroom
Adobe Photoshop (Camera Raw)
Capture One Pro
Darktable
ON1 Photo RAW
On Windows or macOS, you may need RAW codec support to preview the files in File Explorer or Finder.
If you want faster viewing or smaller file size, you can instantly convert 3FR to JPG, PNG, or WebP using OctoConvert’s 3FR Converter.
