Why convert BMP to DNG?
DNG isn't automatically 'better' than BMP in every case – but for Universal RAW — open standard by Adobe, it's the clearer choice. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches. Think of it as future-proofing your files rather than just converting them.
