How to Convert Multiple ORF Images to JPEG?
1. Download and Install reaConverter
reaConverter is a standalone Windows app — download, install, and start converting ORF files in under two minutes. You can also resize, crop, and adjust images during conversion.
2. Load your ORF files
Add ORF files to reaConverter. One file or a thousand, the process is the same. Everything runs locally on your machine.
Drag-and-drop ORFs directly into reaConverter or use the folder browser to load entire directories.
3. Select JPEG as output format
Select JPEG as target format and pick where to save results. You can keep default settings or fine-tune the output.
4. Start ORF to JPEG conversion
Press Convert to begin processing. You can watch the progress or minimize and let it run in the background.
Your converted JPEG files will appear in the destination folder as soon as processing completes.
How ORF and JPEG differ in practice
ORF files hold unprocessed sensor data, so white balance and exposure are still adjustable. Converting to JPEG 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. ORF carries 12 bits per channel and JPEG carries 8, so tonal steps get coarser during conversion. It shows up first in smooth gradients such as skies. If the result will be edited further, move to an 8-bit format only at the very end.
