What is a CR2 file?
The CR2 (Canon Raw 2) format is a proprietary raw image file type developed by Canon Inc., introduced in 2004 with the EOS 20D to supersede the CRW format. Structured on the TIFF (Tag Image File Format) specification, it contains lossless compressed raw sensor data and proprietary binary tags known as 'MakerNotes' that record exposure settings, lens data, and white balance. The format writes data in Big-Endian byte order and was the standard for Canon DSLRs until the introduction of the CR3 format in 2018.
How to open a CR2 file
CR2 files require software capable of parsing Canon's specific sensor data. Canon provides the Digital Photo Professional (DPP) tool for native processing. Third-party support is extensive, with Adobe Photoshop (via Camera Raw), Lightroom, and Capture One being industry standards for decoding CR2. On the OS level, the Microsoft Camera Codec Pack enables viewing in Windows Explorer, while macOS supports CR2 files natively within the Finder and Preview apps via system-level raw engine updates.
