CR2 to PNG: demosaic without the second loss

The demosaic and the 14-bit-to-8-bit reduction happen either way. What PNG avoids is the DCT pass that JPG adds on top: no block artifacts around high contrast edges, no chroma subsampling thinning the colour detail. For a Canon raw being prepared for compositing or print, that matters more than the file size, which typically lands 5-10× above the equivalent JPG.

Pick PNG over JPG when the converted frame still has editing ahead of it, or when it carries fine detail — hair, foliage, text in the scene — that JPG blocking would smear. Pick JPG if the file only needs to be sent or posted.

CR2 to PNG FAQ

Quick answers about compatibility, quality, metadata handling, and the most common reasons to convert CR2 files to PNG.

How do I convert CR2 to PNG?

What is CR2?
CR2 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 CR2 is not supported.

CR2 vs PNG — which format should I use?
CR2 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 CR2 files?
On Windows: Photos, with the free Raw Image Extension from the Microsoft Store. On a Mac: Preview and Photos, natively. Canon RAW. macOS reads it out of the box; Windows needs the Raw Image Extension installed first.

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.
