CANON-RAW to PNG: the cross-family format translation route explained
The CANON-RAW source is interpreted as Canon camera raw captures spanning CRW, CR2, and CR3 generations rather than one interchangeable encoding, then rebuilt for PNG as pixels written losslessly with a full alpha channel available. Renaming the file suffix alone could never accomplish that translation.
Interpreted input - Canon camera raw captures spanning CRW, CR2, and CR3 generations rather than one interchangeable encoding. Required output - Pixels written losslessly with a full alpha channel available.

CANON-RAW source facts versus PNG output requirements
What can fail when CANON-RAW specialized file format is interpreted
Model generation determines the decoder, Picture Style metadata, and lens information that can be interpreted.
What Portable Network Graphics cannot safely promise
PNG is a poor fit for photographic detail, and even without any JPEG-style loss, palette reduction can visibly simplify a smooth gradient.
How the PNG writer handles this route
pixels written losslessly with a full alpha channel available is what gets written, labeled as image/png. Whether that actually opens depends on the receiving application, not on the file extension.
Deciding when CANON-RAW to PNG is the right conversion
Choose PNG when the next app explicitly accepts it and its lossless images and transparency role fits the job better than CANON-RAW.
What changes between the CANON-RAW model and the PNG deliverable
- PNG supports alpha transparency that CANON-RAW never had, so any transparent areas in the result are newly created, not carried over from the source.
- Treat CANON-RAW-specific metadata fields as optional in the PNG result until you have actually confirmed they survived.
Acceptance evidence for the converted PNG
Record the CANON-RAW evidence before conversion
Identify the true extension and camera model before checking color, crop, highlights, lens correction, and EXIF.
