CR2 to DNG online

DNG is Adobe's open RAW container. Converting CR2 to DNG keeps the actual sensor data — so the file stays fully editable — while dropping Canon's proprietary wrapper.

A real RAW conversion, not a JPEG

This is genuine RAW-to-RAW: the sensor data from the CR2 is repackaged into DNG, an openly documented container. The result opens in Lightroom, Capture One and darktable as a RAW file, with the same latitude to recover highlights, lift shadows and set white balance after the fact.

Why bother: DNG is a published standard, so it does not depend on one vendor's software to stay readable, and many workflows standardise on it for archiving. Unlike converting to JPG, nothing about the image is developed or thrown away — only the wrapper changes.

One honest caveat

The conversion relies on knowing your exact camera model. For the Canon bodies in the converter's database you get a true DNG. For a model it does not yet recognise, there is no way to build a valid DNG, so the file falls back to a JPEG carrying a .dng name — a real picture, but not a RAW file.

If keeping RAW data matters, check that the result opens as RAW in your editor. Where the camera is supported, CR2 to DNG is a lossless, future-proof way to store Canon RAW.

Common questions

Is DNG still a RAW file?

Yes. DNG stores the same sensor data as the CR2 in an open container, so it stays fully editable in Lightroom and similar tools — unlike a JPG, which is already developed.

Why would I use DNG instead of keeping CR2?

DNG is an open, documented standard that does not depend on Canon's software to stay readable, which makes it a safer long-term archive format. Many photographers standardise their libraries on it.

Could I get a JPEG instead of a real DNG?

Only if your exact camera model is not yet in the converter's database — then it cannot build a valid DNG and falls back to a JPEG named .dng. For supported Canon bodies you get a true DNG.
