How to Convert Multiple GBR Files to BMP?
1. Download and Install reaConverter

2. Load your GBR files
Open reaConverter and import your .gbr files. No file limits, no slowdowns. Add as many as you need.
Drag files into the window, use the Add Files button, or select entire folders.

3. Select BMP as output format
Select BMP as target format and pick where to save results. You can keep default settings or fine-tune the output.

4. Start GBR to BMP conversion
Hit Convert to process your files. The log window shows progress, timing, and status for every file.

Conversion complete? Your BMP files are saved to the destination folder, ready to use.
How GBR and BMP differ in practice
GBR describes geometry rather than pixels, so it has no inherent resolution. The conversion renders it at whatever size you choose, and that choice is final: enlarging the BMP afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after.
