Why convert TIFF to NEF?

People often ask why bother converting TIFF at all. The short answer: NEF handles Nikon DSLR professional photography noticeably better. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches. The gap becomes more obvious the more TIFF files you're managing at once.
