Why convert WEBP to NEF?

Have you ever tried using a WEBP image on a platform that doesn't support it? That's frustrating. By converting to NEF, you get a universally compatible lossless RAW file that works everywhere. 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.
