DNG to PNG: documented raw, lossless out

Because the DNG specification is public, the decode is predictable in a way proprietary raw is not — no reverse-engineered curve to get wrong. Writing PNG keeps the demosaiced pixels intact, making this the cleanest path from a phone or Adobe-converted raw to something an editor will open without plugins.

Use PNG when the result is going into editing software or a compositing stack. Use JPG when it is going to a person, a page or a print service.

DNG to PNG FAQ

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

How do I convert DNG to PNG?
Upload your DNG image to iFormat and click Convert — it's decoded and re-encoded to PNG in seconds. It's free, adds no watermark, and needs no account. Batch upload is supported, and results download individually or as a ZIP.

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

DNG vs PNG — which format should I use?
DNG is a universal Adobe 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 DNG files?
On Windows: Photos, with the Raw Image Extension. On a Mac: Preview and Photos, natively. Adobe's open RAW format, and the best-supported of them — if a converter or editor reads any RAW, it reads DNG.

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.
