Camera RAW conversion
Convert DNG to BMP
Updated Jul 2026
DNG is the raw file format many cameras save when you shoot in RAW, and BMP is an old uncompressed Windows image format rarely used today. To convert, open the DNG in a converter, choose BMP, and export. Doing it on your own computer keeps the photo and its metadata off someone else's server.

How to convert DNG to BMP
- Open Morphjet and drag in the DNG file, or a whole folder of raw photos at once.
- Choose BMP as the output format.
- Convert. The BMP files are written next to your originals, and nothing leaves your machine.
DNG vs BMP: what actually changes
| DNG | BMP | |
|---|---|---|
| File size | Moderate, often 20 to 50MB depending on the camera | Very large, uncompressed pixel data with no efficiency gain |
| Quality | Lossless, unprocessed sensor data | Lossless, but the image is already flattened and rendered |
| Editable exposure and white balance | Yes, full raw adjustments possible | No, those decisions are already baked in |
| Opens everywhere | No, needs raw-aware photo software | Yes, opens in almost any Windows program, including Paint |
| Keeps camera metadata (EXIF) | Yes, extensive shooting and camera data | Mostly not, BMP has little room for embedded metadata |
When to convert, and when not to
Convert DNG to BMP when you need a raw photo turned into a plain, uncompressed image for an older Windows program, a legacy device, or a workflow that specifically calls for BMP instead of a compressed format like JPG or PNG.
Keep the DNG if you still plan to adjust exposure, white balance, or other raw settings, because once it's a BMP those decisions are locked in and can't be undone.
Why not just use an online converter?
Raw photos from real cameras carry the same kind of metadata as any other digital photo: camera model, exposure settings, and sometimes the exact GPS location of the shot. Upload a DNG to an online converter and that information travels along with it to someone else's server. Converting on your own computer keeps the raw file, and everything embedded in it, on your machine the whole time.
Questions
Does converting DNG to BMP lose quality?
Not in the sense of compression, since both formats are lossless. But exporting a DNG develops the raw sensor data into a fixed image, so you lose the ability to adjust exposure or white balance afterward.
Will the BMP keep the camera's metadata?
Mostly not. BMP has very limited support for embedded metadata, so most of the shooting details stored in the DNG, like camera settings and location, won't carry over.
Why would I want BMP instead of JPG or PNG?
BMP is mainly useful for older Windows software or specific workflows that expect an uncompressed bitmap. For sharing or general storage, JPG or PNG are almost always a better fit since they take up far less space.
Can I convert DNG to BMP without uploading the file anywhere?
Yes. A desktop app like Morphjet reads and converts the raw file locally, so it never has to leave your computer.
Morphjet converts DNG, BMP, and 1,800+ other formats, all on your machine. Launching this July.
