MRW file: what it is and how to convert it to JPG
An .mrw file is a Konica Minolta RAW photo from the DiMAGE 5, 7, A1, A2 and A200 or the Dynax/Maxxum 5D and 7D, cameras sold from 2001 to 2006.

How to open a .MRW file on Windows
- RawTherapee or darktable (free). Both open MRW files, let you set white balance and exposure, and export JPG or TIFF.
- Windows Photos with the Raw Image Extension (free). The Microsoft Store extension shows many older RAW formats; test one MRW file first, as support depends on the model.
- Contenta Converter, for an archive. Drop the folders from your Minolta years and convert every .mrw to JPG, TIFF or PNG in one batch, with camera or auto white balance and the shooting dates kept.
Before you convert MRW files
- What changes in the conversion
A JPG is a finished 8-bit picture: the white balance and exposure chosen at conversion are fixed, and the RAW room to recover highlights later is gone. Converting to 16-bit TIFF keeps more of the tonal range. The .mrw files are not changed, so keep them as negatives if disk space allows; the shooting date and camera data are carried into the output. - What Contenta Converter does with MRW
Contenta Converter decodes MRW with LibRaw, the library behind most RAW editors, and converts folders of them to JPG, TIFF or PNG with camera or auto white balance, optional denoising, resize and rename in one batch. It is a converter rather than a RAW editor: no local adjustments, and it does not write DNG.

| Descriere | MRW is the RAW photo format of Konica Minolta's digital cameras from 2001 to 2006: the DiMAGE 5, 7, 7i, 7Hi, A1, A2 and A200 bridge cameras and the Dynax/Maxxum 5D and 7D DSLRs. It stores the unprocessed sensor data with the camera settings. When Sony took over the camera line in 2006, the format was replaced by ARW. |
| Beneficii | Unprocessed 12-bit sensor data: white balance, exposure and colour can still be chosen when converting. Small files by today's standards. |
| Dezavantaje | An orphaned format: Konica Minolta left the camera business in 2006 and its DiMAGE software is no longer maintained. Current editors still read MRW through LibRaw or Adobe Camera Raw, but that will not last forever, which is a reason to convert archives to TIFF or JPG now. |

Frequently Asked Questions about MRW
Which cameras produce MRW files?
Konica Minolta's DiMAGE 5, 7, 7i, 7Hi, A1, A2 and A200 bridge cameras and the Dynax 5D and 7D (Maxxum in North America) DSLRs, sold from 2001 to 2006. The Sony Alpha cameras that followed write ARW instead.
How do I open MRW files on Windows 11?
Install the free Raw Image Extension from the Microsoft Store for Windows Photos, or use RawTherapee or darktable, both free. To make the photos open everywhere, convert them to JPG or TIFF with Contenta Converter.
Should I convert my MRW archive before the format is forgotten?
It is a sensible precaution. Convert the archive to 16-bit TIFF for a lossless master and to JPG for everyday use, and keep the .mrw files as well. Contenta Converter does each in one batch and keeps the shooting dates.
