Why convert ARW to NEF?
Introduced in 2006 by Sony, ARW was great for its time. But NEF (created in 2003 by Nikon) offers lossless RAW compression and 14-bit per channel – a massive leap forward. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches.
