About CR3 files
Canon's current camera RAW format

Canon EOS R mirrorless cameras and recent Canon DSLRs and compacts.

CR3: settings to change
Before you convert CR3 files, you can adjust: Width, Height, Scale fit, Crop position, Never enlarge, Quality, Lossless, Progressive, Remove metadata, Auto-orient from EXIF, Rotate, and Background.
Limits of the CR3 format
RAW software older than 2018 does not read CR3, and C-RAW files trade some image data for their smaller size.
Common questions about CR3
Why won’t my older software open the CR3 files from my newer Canon? CR3 arrived with cameras from 2018 onward, and programs that were never updated only know the older CR2 layout — converting to JPG or DNG keeps them readable.
Can Windows open CR3 raw files? CR3 is newer than most installed codecs, so Windows often shows an empty preview until a recent Canon or system codec is installed. macOS supports it, and converting to JPG or DNG avoids the codec question entirely.
