Why convert PDF to NEF?

NEF isn't automatically 'better' than PDF in every case – but for Nikon DSLR professional photography, 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. Once you see the size or compatibility difference, going back rarely makes sense.
