How to Convert Multiple CR3 Images to PS?
1. Download and Install reaConverter
reaConverter is a standalone Windows app — download, install, and start converting CR3 files in under two minutes. You can also resize, crop, and adjust images during conversion.
2. Load your CR3 files
Start reaConverter and add your .cr3 files. The software processes everything locally, so your files never leave your computer.
Add files by dragging them in, browsing folders, or using the right-click menu from Windows Explorer.

3. Select PS as output format
Choose PS as the target format. Pick a destination folder or let reaConverter save files alongside the originals.

4. Start CR3 to PS conversion
Then simply press the Convert button and your conversion will begin in no time!

Once the conversion is complete, you can find your PS files in the destination folder you selected.
How CR3 and PS differ in practice
CR3 files hold unprocessed sensor data, so white balance and exposure are still adjustable. Converting to PS 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. PS is a page format, so each CR3 image is placed on a page rather than converted into something else. Two settings decide how the result looks: the DPI, which fixes how large the image sits on the page, and whether a batch becomes one file per image or a single merged document. reaConverter can do either.
