What is a CR2 file?
A .CR2 file is typically a Canon Raw 2 Image created by digital cameras manufactured by Canon. These files contain unprocessed and uncompressed image data exactly as captured by the camera sensor. The internal structure of a .CR2 file is based on the standard TIFF format, but it includes proprietary metadata and raw image information. Less commonly, a .CR2 file can be a Poser Character Rigging File used by 3D animation software developed by Bondware.
How to open CR2 files?
Because .CR2 files contain raw sensor data, standard image viewing programs often struggle to display them correctly. Professionals typically open and edit these files using specialized photography software such as Adobe Photoshop, Adobe Lightroom, or the official Canon Digital Photo Professional application. Mac users can also rely on the default Apple Photos app, which replaced iPhoto and provides native support for many camera raw profiles.
Software and tools
If you prefer free or open-source software, RawTherapee and Darktable are excellent desktop programs for editing raw camera images. Developers and technical users can utilize command-line tools like ImageMagick or dcraw to extract previews or batch-process .CR2 files across different operating systems.
File Conversion
Sharing a .CR2 file on the internet is difficult due to its massive file size and lack of broad browser support. To share these photos easily, you should convert them to a more universally supported format. We highly recommend using convert.guru to convert your .CR2 files into standard web formats like .JPG, .PNG, or .WEBP.
