MRW is Minolta's RAW format — the unprocessed sensor data from DiMAGE and Konica Minolta DSLRs of the early-2000s. That camera line was discontinued in 2006 and folded into Sony's Alpha system, so MRW is now a legacy format that fewer and fewer apps decode. Converting to JPG turns those old RAW captures into 8-bit images that open in any browser, viewer, or editor on any device. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public.

JPG Format at a Glance
| Property | Value |
|---|---|
| Standard | ITU-T T.81 (1992) / ISO/IEC 10918-1 (1994), by the Joint Photographic Experts Group |
| Compression | Lossy, DCT-based (some original data is discarded and cannot be restored) |

| Color | Full color, no alpha/transparency |
| Best for | Sharing, web, prints, archives any app can open |
| Trade-off | Discards the RAW's 12-bit latitude — recover the exposure you want before exporting |
How to Convert MRW to JPG
- Upload Your MRW File: Drag and drop your
.mrwfiles or click "+ Add Files." Batch upload is supported, so an entire shoot can be converted in one pass. - Pick a Quality Preset: Open Advanced Options and choose a Quality Preset (default "Very High") for the JPG, or switch to Specific file size to target an exact size in MB.
- Set Resolution (Optional): Use Resolution Percentage to keep the original pixel dimensions, or pick a Preset Resolution or Width × Height to downscale for web or email.
- Convert and Download: Click "Convert" and download each JPG individually or as a ZIP. No sign-up, no watermark.
Need a lossless, higher-bit-depth result instead of JPG? Use MRW to TIFF for archival masters or MRW to PNG for a lossless web image. Already exported a JPG and need it smaller? Run it through Compress JPG.
Frequently Asked Questions
Will I lose image quality converting MRW to JPG?
You convert from a high-latitude RAW to a lossy 8-bit format, so yes — the file no longer holds the 12-bit editing headroom MRW captures, and JPG's DCT compression discards some data permanently. For a final, viewable image that's usually invisible: at the "Very High" preset the result is visually clean. The latitude only matters if you later need to push exposure or white balance, so set the look you want before exporting. For a non-lossy result, convert to TIFF or PNG instead.
Why won't my MRW file open in modern photo apps?
Minolta and Konica Minolta left the camera business in 2006, so MRW is a discontinued RAW format and newer software often drops support for older proprietary RAW types. Sony continued the camera line under the Alpha brand using its own ARW format, which is what current Sony RAW tooling expects. Converting MRW to JPG sidesteps the compatibility problem entirely — JPG opens in any browser, viewer, or editor.
Is MRW the same as Sony's ARW format?
No. MRW is Minolta/Konica Minolta's RAW format; ARW (Alpha RAW) is Sony's, introduced when Sony took over the SLR line in 2006 — the first Sony Alpha (the A100) was essentially a Konica Minolta 5D design. The formats are not interchangeable: ARW is built on TIFF, while MRW is a separate proprietary container. If you have Sony RAW files, use the ARW to JPG converter instead.
Which Minolta cameras produced MRW files?
MRW came from Minolta's DiMAGE prosumer models (DiMAGE 5, 7, 7i, 7Hi, and the A1/A2/A200) and the Konica Minolta Dynax/Maxxum 5D and 7D DSLRs. Because different bodies wrote slightly different MRW variants, a tool that opens one camera's MRW may not open another's — converting to JPG gives you one consistent format across an entire mixed archive.
Can I convert a whole folder of MRW files at once?
Yes. Add as many MRW files as you like in one go; they're converted with the same quality and resolution settings and returned individually or bundled as a ZIP. The realistic limit on a large batch is upload size and time over your connection, not your device.
Does the JPG keep the EXIF data from my MRW file?
In our testing, converting a Dynax 7D MRW preserved the core EXIF block — camera model, lens, focal length, shutter, aperture, and ISO carry into the JPG. Minolta MakerNote fields, which hold proprietary settings, may not survive since they're specific to the RAW container. If full original metadata matters, keep the source MRW alongside the JPG.
Is converting MRW to JPG actually free, with no watermark?
Yes — no account, no watermark, and no file-count gate. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion; nothing is shared or made public. The output JPG is yours to use anywhere.
