When you need a lossless, editable image from a raw DNG — for retouching, compositing, or print — PNG preserves every pixel after the raw is decoded. Picmal demosaics the DNG sensor data with proper white balance and exports a lossless PNG, all locally on your Mac with no subscription.
| File type | DNG | PNG | Note |
|---|---|---|---|
| DNG raw photo (24MP) | 25 MB | 42 MB | Larger — lossless |
| DNG raw photo (45MP) | 48 MB | 78 MB | Larger — lossless |
| Cropped export | 25 MB | 12 MB | Lossless, cropped |
Export raw DNG captures to PNG when you need a pristine, lossless base for retouching in Photoshop or Affinity.
PNG's alpha support makes it ideal for cutouts and composites built from raw captures.
When a print workflow expects lossless input, PNG from your DNG preserves full quality.
Keep a lossless PNG render alongside your DNG original for editing-ready copies that open anywhere.

Open Picmal, drag your DNG files into the window, select PNG as the output, and click Convert. Picmal decodes the raw data and exports a lossless PNG locally.
Choose PNG when you need lossless quality for editing, compositing, or print, or when you want a clean image with no JPG compression artifacts. Choose JPG for small, shareable files.
Yes. Picmal applies the camera white balance and demosaicing stored in the DNG, so the PNG reflects the intended look rather than a flat raw preview.
Yes — PNG is lossless, so files from a high-resolution DNG can be sizable. The benefit is zero compression loss for further editing.
Yes. Drag a folder of DNG files into Picmal and convert them all to lossless PNG in a single pass.
No. DNG is a raw format that can't be reconstructed from a processed PNG. Picmal converts DNG to standard formats like PNG, JPG, and TIFF, not the reverse.
If you don't need to change formats, Picmal can also compress your files to reduce size:
