IMPLEMENTATION

Viewers responsible for this format

CRW is Canon's older CIFF-based RAW format, used before the TIFF-based CR2 family. Anyfile relies on LibRaw-Wasm to recognize supported cameras, recover metadata and produce a basic inspection image.

Common question

Should a CRW file be renamed to CR2?

No. They use different internal formats; changing the extension does not convert the sensor data.
