Why convert NEF to DNG?

Introduced in 2003 by Nikon, NEF was great for its time. But DNG (created in 2004 by Adobe) offers lossless RAW compression and 16-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.
