What is a .CRW file?
CRW is Canon’s original camera RAW format, predating CR2. Opened in Canon Digital Photo Professional.
- Did you know
- CRW was Canon’s first raw format, used before CR2 arrived in 2004.
- CRW is based on Canon’s own Camera Image File Format (CIFF), a structure distinct from the TIFF foundation Canon later adopted for CR2.
- It was Canon’s first consumer raw format, used on early digital cameras before CR2 took over.
- Being an older, in-house design, CRW is opened most reliably in Canon’s Digital Photo Professional, with patchier support elsewhere.
- The lineage runs CRW, then CR2, then CR3, each step bringing a new internal container as Canon modernised its raw pipeline.
- What Analyser shows you
- Open camera RAW files from Sony (ARW), Canon (CR2, CR3, CRW), Nikon (NEF, NRW), Fujifilm X-Trans (RAF), Sigma Foveon (X3F), Olympus (ORF), Panasonic (RW2), Pentax (PEF), Adobe DNG and many more. Reads full EXIF and lens data, the true sensor resolution, GPS and histograms, recovers the Sony and Nikon shutter actuation count, and develops the RAW - decoding the sensor to a full-resolution image, or extracting the embedded preview when a true demosaic is not available.
