Why convert DIB to NEF?

NEF isn't automatically 'better' than DIB 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. In practice, teams that make this switch rarely go back to DIB for this use case.
