Frequently asked questions

How do I convert DNG to JPG on Mac?

Open Picmal, drag your DNG files or a whole folder into the window, select JPG as the output, set your quality, and click Convert. Picmal decodes the raw data locally on your Mac.

Will the colors look right when converting DNG to JPG?

Yes. Picmal reads the white balance embedded in your DNG files and applies proper demosaicing and gamma, so the JPGs look as intended — not flat like an unprocessed raw preview.

Does converting DNG to JPG lose quality?

Raw-to-JPG is a one-way render: JPG is 8-bit and compressed, so you give up the raw file's editing latitude. At 90–100% quality the result looks excellent — keep your DNG originals if you'll edit further.

Can I batch convert a whole shoot of DNG files?

Yes. Drag hundreds of DNG files or an entire folder into Picmal and convert them all to JPG in one pass — ideal for culling and delivering shoots.

Do I need Lightroom to convert DNG to JPG?

No. Picmal decodes DNG directly on your Mac. It's a one-time purchase of $15.99 — no Adobe subscription required just to get shareable JPGs.

Can Picmal convert JPG back to DNG?

No. DNG is a raw format — no software can rebuild true raw sensor data from a JPG. Picmal converts DNG to standard formats like JPG, PNG, and TIFF, not the other way around.
