CR3 to PNG: lossless out of CRX

Decoding CRX and writing PNG keeps every pixel the demosaic produced. The result is a large file — a 45-megapixel body yields well over 100 MB — because PNG stores each of those pixels without a lossy transform. For a Canon raw that is going into a composite or a retouch, that is the point.

Use PNG when the frame will be layered, masked or retouched after conversion. If it is going straight to a web page or a messaging app, the size is wasted and JPG is the better target.

What is CR3?
CR3 is a Canon camera RAW file, typically used for professional editing before export. Converting it to PNG makes the file easier to open, share, or upload where CR3 is not supported.

CR3 vs PNG — which format should I use?
CR3 is a Canon camera RAW file best for professional editing before export. PNG is a lossless format with transparency support best for logos, screenshots, and graphics with sharp edges. Use PNG when a website, form, or app requires it, or when you need PNG's specific strengths like smaller file size, wider compatibility, or transparency support.

How do I open CR3 files?
On Windows: Photos, with the Raw Image Extension — and only on recent Windows builds. On a Mac: Preview and Photos on recent macOS. Canon's newer RAW format. Support lags CR2 noticeably, so older software that opens CR2 fine may still reject CR3.

Is PNG a good choice for camera RAW?
It depends what you need. PNG is lossless, so it will not add compression artefacts — useful if the image is heading for further editing or compositing. The files are large, though, and PNG stores 8 bits per channel, so it cannot hold the full tonal range of the RAW either. For sharing or printing, JPG is usually the more practical target; for archiving, keep the RAW itself.

Should I edit the RAW first?
Yes. Exposure and white-balance corrections have far more room to work while the file is still RAW. Once converted, you are editing a fixed 8-bit image with much less recoverable detail in the highlights and shadows.

Why is the PNG larger than the original RAW?
It can be. RAW files use compression tuned to sensor data, while PNG stores every pixel of the fully demosaiced image — three or four channels at full resolution. A 25 MB RAW becoming a 40 MB PNG is normal, and is a good reason to use JPG unless you specifically need lossless output.
