Why convert DIB to DNG?

Compatibility, file size, and quality rarely align perfectly – DNG gets closer to that balance than DIB for Universal RAW — open standard by Adobe. 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.
