ARW to PNG: Sony raw into a lossless frame

Same decode, different destination. PNG keeps the demosaiced result pixel for pixel, which is what you want if the frame is going into a retouch where each save would otherwise stack another round of JPG loss. Expect roughly 8× the size of a high quality JPG from the same ARW.

Use PNG when the converted file is an intermediate rather than a deliverable — something that will be opened, edited and saved again. For a finished frame, JPG is smaller and visually equivalent.

ARW to PNG FAQ

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

How do I convert ARW to PNG?

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

ARW vs PNG — which format should I use?
ARW is a Sony 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 ARW files?
On Windows: Photos, with the Raw Image Extension. On a Mac: Preview and Photos, natively. Sony RAW. Newer camera bodies sometimes need updated software even when older ARW files open.

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.
