BMP to RAW

Looking to convert BMP to RAW? Here's the honest answer — and what works instead.

You can't convert BMP to RAW — and no tool genuinely can. Here's why.

Why BMP to RAW isn't possible

1

RAW is sensor data, not a picture

A RAW file is the unprocessed data captured straight off a camera's image sensor the instant you press the shutter. A BMP is an already-processed, finished image — the original sensor information is long gone and can't be recreated.

2

It's tied to a specific camera

Each RAW format — Canon CR2, Nikon NEF, Sony ARW, Fuji RAF and dozens more — is proprietary to one camera maker and model. There is no single universal "RAW" file to convert into.

3

The detail can't be rebuilt

Converting to RAW can't bring back the extra dynamic range, color depth or highlight recovery that real RAW holds — that data was never in your BMP. You'd only get a larger file with none of the benefits.

So what are the actual RAW formats?

"RAW" isn't a single format — it's dozens of camera-maker-specific ones. A real RAW file is always one of these, straight from the camera:

Format details

BMP is an uncompressed raster format that stores pixel data with no quality loss, producing large files. It is common on Windows.

Extension.bmp
MIME typeimage/bmp
TransparencyNo

BMP opens in most image viewers and editors on Windows and Mac.

A raw file is the unprocessed data straight from a camera’s sensor, keeping maximum detail and dynamic range before it is developed into a JPG or PNG. “RAW” isn’t one format — each maker has its own (CR2, NEF, ARW…).

RAW files open in Lightroom, Photoshop / Camera Raw, Capture One and each camera maker’s software.

Frequently asked questions

No. RAW is the unprocessed data a camera's sensor records at the moment of capture — it can't be generated from an already-processed BMP, or from any finished image. Software converts from RAW, never into it.

BMP is a finished, ready-to-view image. A RAW file holds the original sensor data with far more dynamic range and editing latitude — but it only ever comes straight out of a camera, not from a converter.

DNG (Adobe Digital Negative) is an open RAW container. You can convert a camera's proprietary RAW — CR2, NEF, ARW and so on — into DNG, but you still can't turn a regular BMP into RAW.

RAW files open in Adobe Lightroom, Photoshop and Camera Raw, Capture One, and each maker's own software — Canon DPP, Nikon NX Studio, Sony Imaging Edge and more.

Yes — that direction works. Use our converter to turn CR2, NEF, ARW, DNG and other RAW files into JPG, PNG or TIFF.

No. You can't recover detail, dynamic range or color depth that was never captured. Your BMP already contains all the data it has.
