Why convert DDS to NEF?

Introduced in 1999 by Microsoft, DDS 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.

Transparent areas will be filled with white background

This format requires a WebAssembly decoder — allow a moment for library loading
