Why convert JPEG to NEF?
JPEG served its purpose well, but modern workflows increasingly favor NEF for Nikon DSLR professional photography. The shift is worth making. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches. It's worth doing once properly rather than repeatedly fighting JPEG limitations.
