How to Convert Multiple FIT Images to JP2?
1. Download and Install reaConverter
reaConverter installs quickly on any Windows PC. No dependencies, no bloatware — just a clean setup that's ready to use immediately. Need edits? Resize, rotate, or add watermarks during conversion.
2. Load your FIT files
Launch reaConverter and load the FIT files you want to convert. Add a few files or thousands, batch processing handles them all.
Drag-and-drop FITs directly into reaConverter or use the folder browser to load entire directories.

3. Select JP2 as output format
Set JP2 as output format and select where to save your converted files. Customize quality settings if needed.

4. Start FIT to JP2 conversion
Press Convert to begin processing. You can watch the progress or minimize and let it run in the background.

Your converted JP2 files will appear in the destination folder as soon as processing completes.
What changes when you convert FIT to JP2
FIT stores 32-bit greyscale covering the full dynamic range of the scan, and JP2 shows 8 bits. The conversion applies a window level, so what ends up visible depends on the window you choose. Decide separately whether patient metadata should be copied to the output or stripped from it. One FIT file can hold several pages or frames, while JP2 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.
