About DNG (ADOBE) to OPENEXR Conversion
DNG (introduced 2004) and EXR (introduced 2003) are both image formats, but they differ in important ways. DNG (Digital Negative) is Adobe's open RAW format designed for long-term archival of digital photographs. EXR (OpenEXR) is a high-dynamic-range format used in VFX, film, and 3D rendering pipelines.
Full Name: DNG uses Digital Negative, while EXR uses OpenEXR Image. Compression: DNG uses Lossless, while EXR uses Lossy & Lossless. Transparency: DNG uses No, while EXR uses Yes.
When you convert DNG to EXR, the goal is to convert between formats quickly. Converting DNG to EXR maintains high quality with CocoConvert's optimised encoder settings. Understanding these technical differences helps you choose the right format for your workflow.
Your DNG file is decoded and re-encoded as EXR. The conversion involves 4 steps: (1) your dng file is uploaded and the format is validated, (2) the file content is decoded into its raw representation, (3) the data is re-encoded in exr format with optimal settings, (4) the converted file is ready for download.
CocoConvert's converter handles the entire pipeline server-side using FFmpeg, Sharp, and qpdf — battle-tested libraries used by streaming platforms and enterprise tools. Files are encrypted in transit and deleted within 24 hours.
This conversion is ideal when you When you specifically need a EXR file for your workflow. For the opposite direction, CocoConvert also supports EXR to DNG conversion.

Download result
Grab your converted .exr file. Multiple output files can be downloaded together.
What Happens When You Convert DNG (ADOBE) to OPENEXR
Your DNG image is decoded into raw pixel data, then re-encoded as EXR.
Your DNG file is decoded — the compressed/stored pixel data is expanded into raw RGB pixels
Pixels are re-encoded using OpenEXR Image's lossless compression
Metadata (EXIF, ICC profiles) is transferred where EXR supports it
The EXR file is saved and ready for download
