How to Convert Multiple ORF Images to ICO?
1. Download and Install reaConverter
reaConverter is a standalone Windows app — download, install, and start converting ORF files in under two minutes. Built-in editing tools let you resize, crop, or watermark as you convert.
2. Load your ORF files
Open reaConverter and add your ORF files. You can load individual files, entire folders, or even nested subfolders.
Select ORFs from a folder or drag-and-drop them directly into the reaConverter window.
3. Select ICO as output format
Pick ICO as output format and choose the destination folder where you want to save new .ico files.
4. Start ORF to ICO conversion
Press the Convert button and reaConverter takes care of the rest. Processing time depends on file size and volume.
After processing, find all your new .ico files in the output location. The log shows details for each conversion.
How ORF and ICO differ in practice
ORF files hold unprocessed sensor data, so white balance and exposure are still adjustable. Converting to ICO 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 ICO 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.
