What a CR2 file is
CR2 is Canon's RAW format from roughly 2004 to 2018: the EOS DSLRs from the 5D and 7D series to the Rebel (xxxD) and xxD bodies, and the PowerShots of the same years. It is a TIFF-based file holding the sensor's 12- or 14-bit values, losslessly compressed, plus the camera's own JPEG.
Cameras that record CR2 include the EOS 5D Mark II, III and IV, 6D and 6D Mark II, 7D and 7D Mark II, 80D, 77D, Rebel T6i/T7i (750D/800D), 1D X.
The JPEG inside a CR2
A CR2 file also carries the JPEG the camera made: full size: 5760 × 3840 on an EOS 5D Mark III and 5472 × 3648 on an EOS 6D. Canon also stores a 464 × 309 uncompressed thumbnail; the converter skips it and uses the real JPEG.
Converting CR2 to JPG here
- Drop one or many CR2 files on the converter, or choose them.
- Keep “Develop the RAW” for the full sensor, or choose “Use the camera's JPEG” for its exact look.
- Choose JPG (and its quality) or a 16-bit TIFF, the size, and the brightness if the camera's was not what you wanted.
- Press Convert. Each file can be downloaded as soon as it is ready, or all of them as one ZIP.
What it does not do
- No lens corrections: distortion and vignetting that the camera removes from its own JPEG stay in the developed picture (most visible on Micro Four Thirds).
- No sharpening and no noise reduction: the developed picture is what the sensor recorded, which at 100 % looks softer and grainier than a camera JPEG.
- No picture styles or film simulations: the developed colour is neutral. The camera's own JPEG keeps them.
- Apple ProRAW and other already-demosaiced (linear) DNGs are refused by name, not guessed at.
- Memory: a 24-megapixel file needs about 0.5 GB while it is developed, a 60-megapixel one about 1.3 GB. Files are converted one at a time so a batch does not add up.
