What is a .cr2 file?

CR2 is a proprietary raw image file format developed by Canon for its digital cameras. It captures minimally processed image data directly from the camera's sensor, offering greater editing flexibility and image quality than standard JPEG files. These files contain extensive metadata, including camera settings and lens information, making them ideal for professional photographers seeking maximum control over their images.

Common Problems with .cr2 Files

⚠️ File won't open in image viewer.

Ensure you have installed the latest version of your image viewer or a dedicated RAW photo editor, as CR2 files require specific software support.

⚠️ Image quality is lower than expected after editing.

Since CR2 files are raw, excessive editing or saving in a lossy format can degrade quality. Always edit non-destructively and save to a high-quality format like TIFF for final output if needed.

⚠️ Cannot import CR2 files into older editing software.

Older software may not support the CR2 format or specific versions of it. Update your software, use a conversion tool, or export from Canon's DPP to a more compatible format like DNG or JPEG.
