Why convert DNG to BMP?

The main issue with DNG is lack of browser support. Converting to BMP fixes this by providing broad compatibility across devices and software. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches. The gap becomes more obvious the more DNG files you're managing at once.
