About the CRW format
RAW — Canon RAW (CRW)
CRW is Canon's original proprietary RAW format, used on early Canon digital cameras before the CR2 format was introduced. It stores unprocessed sensor data and remains widely encountered when working with archives from early-2000s Canon DSLRs.
Common uses
- Digitizing legacy Canon camera archives
- Post-production of early DSLR photos
- Historical photography projects
- Converting old RAW libraries to modern formats
About the HEIF format
HEIF — High Efficiency Image File Format
HEIF is the container format standard developed by MPEG for storing images encoded with HEVC (H.265). While HEIC is the specific Apple implementation, HEIF is the underlying open standard that supports a broader range of encoders including AV1 (AVIF).
Common uses
- Cross-platform modern image delivery
- HDR and wide color gamut images
- Image sequences and live photo storage
- Next-generation camera output formats
