CR2 is Canon's in-camera RAW
CR2 is the raw sensor data a Canon 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 CR2 from a finished DNG.
Looking to convert DNG to CR2? Here's the honest answer — and what works instead.

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.
DNG opens in Lightroom, Photoshop, Camera Raw and most pro photo editors.
CR2 is Canon’s older raw photo format, holding unprocessed sensor data from EOS cameras for maximum editing flexibility.
CR2 opens in Canon DPP, Lightroom, Photoshop and most raw editors.
No. CR2 stores the raw signal a Canon sensor recorded at capture. A DNG is a finished image with that data already baked in and discarded — there's nothing for a converter to reconstruct.
RAW formats like CR2 give maximum editing latitude — but only when they come straight from the camera. Converting a DNG to CR2 would just wrap a finished image in a RAW container, with none of the benefits.
DNG is an open RAW container. You can convert a camera's own RAW (including CR2) into DNG, but you still can't turn a regular DNG into CR2 or any real RAW.
DNG converts cleanly to PNG, JPG, TIFF and WEBP — free, no sign-up, no watermark.
