Why convert DNG to BMP?
Some old Windows software, embedded tools and legacy pipelines only accept the uncompressed BMP format and have no idea what to do with a RAW sensor file. Converting DNG to BMP runs the full RAW pipeline and repackages every pixel into that simpler container — much larger than the DNG, but readable by software that's never heard of RAW formats at all. It happens entirely in your browser; nothing is uploaded.
DNG vs BMP at a glance
DNG is Adobe's open RAW standard — a universal container for camera sensor data designed to remain readable decades from now, supported by virtually every photo editing application. BMP is Windows' raw bitmap format — pixel data stored uncompressed, which makes files enormous.

DNG to BMP — frequently asked questions
Is this DNG to BMP converter really free?
Yes — completely free, with no sign-up, no watermarks and no daily limits.
Are my DNG files uploaded to a server?
No. The conversion happens entirely on your device using your browser's built-in image engine. Your DNG files never leave your computer or phone — which is also why the conversion is nearly instant.
Why is my BMP so much bigger than the DNG?
BMP stores every pixel's color raw with no compression at all, while DNG holds compact sensor data. A large size increase from DNG to BMP is normal and expected.
Why would I need a BMP instead of a DNG?
Mostly for compatibility with older Windows programs, embedded systems or technical tools that expect a simple, uncompressed bitmap and have no RAW decoder of their own.
