How to Convert Multiple DICOM Images to JPEG?
1. Download and Install reaConverter
reaConverter is a standalone Windows app — download, install, and start converting DICOM files in under two minutes. You can also resize, crop, and adjust images during conversion.
2. Load your DICOM files
Start reaConverter and add your .dicom files. The software processes everything locally, so your files never leave your computer.
Add files by dragging them in, browsing folders, or using the right-click menu from Windows Explorer.

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

4. Start DICOM to JPEG conversion
Then simply press the Convert button and your conversion will begin in no time!

Once the conversion is complete, you can find your JPEG files in the destination folder you selected.
How DICOM and JPEG differ in practice
DICOM stores 16-bit greyscale covering the full dynamic range of the scan, and JPEG 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. DICOM carries 16 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.
