Why convert NEF to DNG?
DNG (Digital Negative) is an open, publicly documented raw format maintained by Adobe. Converting from NEF removes the dependency on Nikon-specific decoders, which is useful for long-term archiving or managing raw files from multiple camera brands in a single workflow.

- Raw data is preserved - DNG keeps the unprocessed sensor data from the
.nef; it is not a rendered image and still requires raw-capable software to develop. - Nikon MakerNote metadata (camera model, lens, exposure, ISO, Picture Control settings) is retained in the DNG.
- The
Embed Original Raw Fileoption in Adobe DNG Converter stores the source.nefinside the DNG verbatim, roughly doubling the file size but making the conversion fully reversible; without it, keep your.neffiles backed up separately.
