What is a .DNG file?
DNG (Digital Negative) is Adobe’s open, manufacturer-independent camera RAW format. Opened in Adobe Lightroom and most raw editors.
- Did you know
- Adobe created DNG in 2004 as a universal, open alternative to each maker’s proprietary raw format.
- DNG is built on the TIFF/EP imaging standard, so a DNG file is structurally a specialised, well-documented variant of a TIFF.
- After more than two decades, DNG was finally published as an international standard, ISO 12234-4, in 2026, putting it on the same archival footing as TIFF and PDF/A.
- The United States Library of Congress lists DNG as a recommended format for long-term raw image preservation.
- A DNG can wrap a camera maker’s original proprietary raw data inside it, letting you archive in an open format without throwing the source file away.
- What Analyser shows you
- Open camera RAW files from Sony (ARW), Canon (CR2, CR3, CRW), Nikon (NEF, NRW), Fujifilm X-Trans (RAF), Sigma Foveon (X3F), Olympus (ORF), Panasonic (RW2), Pentax (PEF), Adobe DNG and many more. Reads full EXIF and lens data, the true sensor resolution, GPS and histograms, recovers the Sony and Nikon shutter actuation count, and develops the RAW - decoding the sensor to a full-resolution image, or extracting the embedded preview when a true demosaic is not available.
- Open a .DNG file
- Drag a .DNG file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
