How to Convert Multiple GEOTIFF Files 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.
2. Load your GEOTIFF files
Launch reaConverter and load the GEOTIFF files you want to convert. Add a few files or thousands, batch processing handles them all.
Drag-and-drop GEOTIFFs directly into reaConverter or use the folder browser to load entire directories.

3. Select GBR as output format
Set GBR as output format and select where to save your converted files. Customize quality settings if needed.

4. Start GEOTIFF to GBR conversion
Press Convert to begin processing. You can watch the progress or minimize and let it run in the background.

Your converted GBR files will appear in the destination folder as soon as processing completes.
How GEOTIFF and GBR differ in practice
One GEOTIFF file can hold several pages or frames, while GBR holds one image each. reaConverter writes a separate output file per page and numbers them, so a single input can produce a whole folder of results.
