Looking to turn a DNG into a RW2 file? Here's the honest answer — and what actually works instead.
You can't convert DNG to RW2. RW2 is a camera's own RAW format — it only ever comes out of the camera.
RW2 is the raw sensor data a Panasonic camera writes at the moment of capture. It's produced by the camera's own hardware and firmware — software can read it, but nothing can manufacture a genuine RW2 from a finished DNG.
Your DNG is a developed, final image. The extra sensor information a RW2 carries — wider dynamic range, full color depth, untouched highlights — was discarded when the photo was first saved, and can't be put back.
RW2 is proprietary to Panasonic. Even other RAW formats (NEF, ARW, RAF…) aren't interchangeable with it — there is no universal "save as RAW" that produces a real RW2.
Every real RAW file is one of these camera-maker-specific formats, written by the camera itself:
DNG is Adobe’s open, universal raw format. It stores unprocessed sensor data in a standardised container any modern editor can open — ideal for archiving photos.
