You're shooting with a newer Canon camera — EOS R, R5, R6, R7, R10, or similar — and the RAW files are .cr3. This is Canon's modern RAW format, replacing CR2 with a new container based on the ISO Base Media File Format (the same foundation as MP4 and HEIF).
CR3 offers improved compression options (including Canon's lossy C-RAW mode for smaller files with minimal quality loss), faster read/write speeds, and support for features like Dual Pixel RAW data for focus fine-tuning. The new container format also future-proofs Canon's RAW files as the industry moves toward standardised media containers. Internally, the sensor data is still the same unprocessed capture — full dynamic range, full colour depth.
Adobe Lightroom (subscription) supports CR3 from all Canon cameras. Canon's Digital Photo Professional (free) handles CR3 natively with Canon-specific features like Digital Lens Optimizer. Darktable (free, open-source) supports most CR3 variants. Make sure your editing software is up to date — CR3 from newly released cameras may require the latest version.
