This extension is characterized a raster graphic format which is recognized by many programs today. In comparison with other bitmap formats, JPEG and GIF, BMP keeps color data for each pixel in the image and doesn't compress images to decrease a file size. That is what makes it perfect file format for printable images.

Used it to convert Adobe DNG files for a legacy imaging pipeline that only accepts BMP. Worked perfectly on every file, including 16-bit DNGs.

DNG to BMP Converter — Frequently Asked Questions ▼

What is a DNG file?

DNG (Digital Negative) is Adobe's open RAW image format. Many photographers convert proprietary camera RAW (CR2, NEF, ARW) to DNG for long-term archival. Cameras from Leica, Pentax, and many phones produce DNG natively.

Why convert DNG to BMP?

Convert when you need a Windows-native uncompressed bitmap — for legacy Windows software, resource compilers, embedded displays, or any environment that does not support modern image formats.

How do I convert DNG to BMP online?

Upload your .dng file using the button above. The converter demosaics the RAW data, applies the embedded white-balance metadata, and writes a 24-bit Windows BMP for download.

Is the BMP very large?

Yes — BMP is uncompressed. A 24 MP DNG produces a 70-100 MB BMP. For most modern uses PNG or TIFF is a better choice; pick BMP only when specifically required.

Can the BMP have transparency?

Standard 24-bit BMP does not support alpha. The 32-bit BMP variant does, but support varies. Total Image Converter exposes both options.

Can I batch-convert DNG files?

Yes — Total Image Converter processes folders: TotalImageConverter.exe C:\dng C:\bmp -c bmp converts every DNG in C:\dng without opening the GUI.

Are uploads private?

Files are deleted after you download the result. They are never indexed or shared. For confidential RAW images, run conversion locally with Total Image Converter.
 

 

Convert DNG to BMP — Adobe RAW to Windows Uncompressed Bitmap

DNG is Adobe's open RAW image format — supported by every Adobe app but unreadable by legacy Windows software. Converting DNG to BMP gives you the Windows-native uncompressed bitmap that resource compilers, embedded systems, and old desktop software require. Drop your .dng file above.

What Is DNG?

DNG (Digital Negative) is Adobe's open RAW format, used by Leica, Pentax, Ricoh, Hasselblad, many smartphone cameras, and as a common archival target for converting proprietary RAW files. Native support exists in every Adobe product and most modern image editors.

What Is BMP?

BMP (Windows Bitmap) is the uncompressed image format Microsoft built into Windows in 1990. Every Windows GDI function, every Visual Studio resource editor, every legacy Windows application, and every embedded display system supports BMP natively. Files are large but rendering is instant.
