How to Convert Multiple CIFF Images to HRU?
1. Download and Install reaConverter
First, grab reaConverter from the download button below. Installation is fast, and the software runs offline — no account or signup needed. Need edits? Resize, rotate, or add watermarks during conversion.
2. Load your CIFF files
Start reaConverter and add your .ciff files. The software processes everything locally, so your files never leave your computer.
Select CIFFs from a folder or drag-and-drop them directly into the reaConverter window.

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

4. Start CIFF to HRU 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 .hru files in the output location. The log shows details for each conversion.
