RAW is a collection of uncompressed image formats including CR2. It is a file type used by some popular Canon digital cameras, such as EOS400D, EOS450D and more. To help you understand what Canon CR2 is, we will compare it with JPG below:

2. Quality. CR2 usually record 12 bits color or 36 bits per location. JPG stores exactly 8 bits per color or 12 bits per location. Even you zoom out a CR2 image file, it won’t become blurry.

3. Compression. CR2 is a RAW format. It means that the image files contain extensive data and information captured by camera processors. JPG is a compressed image format instead. That makes CR2 better for adjustment and editing.

4. File size. Since CR2 is uncompressed format and stores a lot of information, the file size is much larger than JPG.

Sometimes, you view the image stored in CR2 and JPG respectively, but the latter may look better. That is due to Canon CR2 files just store the original image data. But JPG will become sharper and higher in contrast while compression. Therefore, CR2 is not suitable to print from your camera.
