How to Convert Multiple CR2 Images to GBR?
1. Download and Install reaConverter
reaConverter is a standalone Windows app — download, install, and start converting CR2 files in under two minutes. Built-in editing tools let you resize, crop, or watermark as you convert.
2. Load your CR2 files
Open reaConverter and import your .cr2 files. No file limits, no slowdowns. Add as many as you need.
Drag-and-drop CR2s directly into reaConverter or use the folder browser to load entire directories.
3. Select GBR as output format
Pick GBR as the output format. Set the destination folder and optionally configure resolution, quality, or file naming.
4. Start CR2 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 CR2 and GBR differ in practice
CR2 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. CR2 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.
