How to Convert Multiple DNG Images to GBR?
1. Download and Install reaConverter
reaConverter installs quickly on any Windows PC. No dependencies, no bloatware — just a clean setup that's ready to use immediately. You can also resize, crop, and adjust images during conversion.
2. Load your DNG files
Open reaConverter and add your DNG files. You can load individual files, entire folders, or even nested subfolders.
Select DNGs from a folder or drag-and-drop them directly into the reaConverter window.
3. Select GBR as output format
Pick GBR as output format and choose the destination folder where you want to save new .gbr files.
4. Start DNG to GBR conversion
Press the Convert button and reaConverter takes care of the rest. Processing time depends on file size and volume.
After processing, find all your new .gbr files in the output location. The log shows details for each conversion.
DNG to GBR: what carries over and what does not
DNG files hold unprocessed sensor data, so white balance and exposure are still adjustable. Converting to GBR bakes those decisions into the pixels, and highlight recovery is no longer available afterwards. Set white balance and exposure before the run rather than after. DNG is made of pixels and GBR is a geometry format, so the two describe images in fundamentally different ways. Check the result before sending it downstream: what matters is whether the output contains editable geometry or a picture placed inside a GBR container, and that determines whether a CAD or design tool can work with it.
