Why convert DNG to ARW?

Introduced in 2004 by Adobe, DNG was great for its time. But ARW (created in 2006 by Sony) 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.
