What Is a DNG File?
DNG (Digital Negative) is Adobe’s open RAW image format. Like any RAW file, a .dng holds the unprocessed sensor data from the camera — maximum editing latitude, no baked-in processing. Unlike Nikon’s .NEF or Sony’s .ARW, the format is openly documented and not tied to one manufacturer.
You’ll encounter DNG files from three sources:
- Cameras and phones that shoot DNG natively — many smartphones (including iPhone ProRAW and most Android RAW modes) and some cameras (Leica, Pentax, drones) save DNG directly
- Conversions — Adobe’s free DNG Converter turns any proprietary RAW into DNG
- Mobile Lightroom presets — the surprise third case, explained below
Why Do Lightroom Mobile Presets Come as DNG Files?
The free Lightroom mobile app can’t import .xmp preset files — but it can import photos, and a DNG carries its develop settings in its metadata. So preset makers ship a small DNG photo with the edit applied; you import it, copy the settings, and save them as a preset. Our mobile preset installation guide walks through it.
Desktop presets use .xmp files instead — settings only, no photo. See what is an XMP file for that half of the story.
How to Open a DNG File
- Editing apps — Lightroom (desktop and mobile), Photoshop/Camera Raw, Capture One, and most serious editors open DNG directly
- Operating systems — recent macOS and Windows preview DNG out of the box; older systems may need a codec
- Inspect the metadata — upload a DNG to the EXIF data viewer to see the camera, settings, and any embedded develop adjustments without installing anything
How to Convert DNG to JPG
The everyday route: open the DNG in any editor (Lightroom, Photoshop, even the free Adobe DNG Converter workflow) and export as JPG. On a phone, sharing a DNG from Lightroom mobile exports a JPG automatically. Remember that the export bakes in whatever develop settings are active — a “flat” conversion and an edited one can look very different from the same file.
DNG vs. Proprietary RAW: Should You Convert?
Arguments for DNG: one open format instead of dozens of proprietary ones, slightly smaller files, no sidecar clutter (edits embed in the file), and long-term readability. Arguments against: conversion takes time, some manufacturer software works best with native RAW, and camera-brand tools may not read DNG. There’s no wrong answer — but if you archive for decades, an openly documented format is the safer bet.
Does a DNG Contain My Location and Camera Info?
Yes — DNG files carry full EXIF metadata: camera, lens, settings, timestamps, and GPS coordinates if your device recorded them (here’s how to see where a photo was taken). If that matters to you, strip the metadata before sharing.
