How to Convert Multiple GEOTIFF Files to JXR?
1. Download and Install reaConverter
reaConverter is a standalone Windows app — download, install, and start converting GEOTIFF files in under two minutes.
2. Load your GEOTIFF files
Add GEOTIFF files to reaConverter. One file or a thousand, the process is the same. Everything runs locally on your machine.
You can drag-and-drop files, browse to a folder, or add entire directory trees including subfolders.

3. Select JXR as output format
Select JXR from the output format list and set your destination folder. You can also adjust quality and compression settings.

4. Start GEOTIFF to JXR conversion
Click the Convert button to start. reaConverter will process all your files with the settings you selected.

When finished, your new .jxr files will be waiting in the destination folder.
Before you convert GEOTIFF to JXR
GEOTIFF describes geometry rather than pixels, so it has no inherent resolution. The conversion renders it at whatever size you choose, and that choice is final: enlarging the JXR afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after. One GEOTIFF file can hold several pages or frames, while JXR holds one image each. reaConverter writes a separate output file per page and numbers them, so a single input can produce a whole folder of results.
