Why convert NEF to DNG?

Not all image formats age equally. NEF (2003) predates many of today's requirements, while DNG directly addresses 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.
