Why convert DNG to ARW?

Not all image formats age equally. DNG (2004) predates many of today's requirements, while ARW directly addresses Sony Alpha mirrorless photography. 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.
