HOW TO OPEN?
What is a CR2 file? It is a standard file extension for all pictures you take with a Canon camera. The format’s full name is Canon Raw 2. Many photographers are actively using CR2 files since they save all the digital info from the original shot. This format is created on the basis of the TIFF file, which is known for delivering qualitative pictures as well.
CR2 file is a raster one, meaning that the info about a picture is saved in the form of the pixel grid. One pixel stands for a separate color. Since .cr2 is a RAW file format, it doesn’t compress any info from a picture and leaves the widest possible space for picture post-production. The information is stored so the actual picture is presented as a gray-scale encoded color filter array. To get an RGB image, the array must be deconvoluted. Moreover, CR2 files include metadata about a picture, such as a lens and a camera used, WB settings, etc.
The size of an unprocessed CR2 file is rather large. The file will consume plenty of system resources when you are editing it. That’s why, if you take shots for your Instagram profile or for a family album, which doesn’t require printing pictures in a very big size, the .cr2 file extension won’t be suitable for you. In this case, saving shots in JPEG will be the most optimal option.
But if you are a professional shooter, who takes pictures for commercial purposes, the CR2 file format will be an ideal variant. This format will come in handy in cases when the pictures contain a lot of white and light details. It allows adjusting the picture up to five stops of light and fixing the white balance.
Some of the recently released versions of well-known OS automatically support the majority of RAW picture types. So if you are wondering how to open CR2 files in Windows 10, now you can view them straight in the system’s Photos app. Besides, you can enable the visibility of thumbnails in the Files Explorer after installing several plug-ins. Opening CR2 file is now also possible on iOS 11 and macOS High Sierra. You can edit pictures in Preview and Photos apps, which come integrated into the OS. In case you are searching for a professional CR2 file editor or viewer, pay attention to the following programs.

The majority of professional picture/video editing software, as well as Adobe programs, is capable of opening CR2 file. But keep in mind that you have to fiddle with the settings first and then start working.
CR2 files are already compressed to approximately 50 or 60%. The entropy theory states that lossless compression may be nearly 1.25%. Therefore, the size of CR2 files, as the majority of other RAW files, can be reduced only in case you get rid of some pixels or try to perform lossy compression.
Not only Canon provides its own RAW picture extension. Other renowned camera brands have created their own formats too, for instance, Sony – ARW, Panasonic – RW2, Nikon – NEF, Fujifilm – RAF. All of these formats may be called CR2 file analogs.
