Why convert ARW to DNG?

DNG isn't automatically 'better' than ARW 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. This kind of format decision tends to matter more as a project scales up.
