What is a .cr2 file?

File extension details and usage information

CR2 files are raw image files created by Canon digital cameras. They contain minimally processed data directly from the camera's sensor, preserving a high level of detail and dynamic range. This means CR2 files retain more information than standard JPEG images, allowing for greater flexibility in post-processing. Photographers often use CR2 files to adjust white balance, exposure, contrast, and other settings without significantly degrading the image quality. Because they are raw files, CR2 files are not directly viewable by most image viewers and require specialized software for processing and conversion. The format stores metadata about the image, including camera settings, date, and time. CR2 files are based on the TIFF file format and are typically larger in size than JPEG files due to the uncompressed or losslessly compressed nature of the data. They are essential for professional photographers who require maximum control over their images during editing.

  • Adobe Photoshop

Open the file in compatible software and look for options such as Save As, Export, or Convert. If no export option is available, the file may require a specialized converter or the original application that created it.

  1. Verify that the file extension is correct.
  2. Install or update compatible software.

Only open files from trusted sources. Before opening a .cr2 file, scan it with antivirus software, verify that the file extension is expected, and avoid running unknown executable, installer, macro-enabled document, or script files.
