Convert DCM to PNG in a large batch

I have 2698 DCM files … voxel data of two brain scans, and I’d like to be able to convert them into PNGs or another normal image file type so I can bring it into Blender as a volumetric texture and do stuff with it. Any suggestions on a program that can batch convert these files? I’m on Windows.

… looks like they’ve provided me with software to convert as well. Sorry for asking too early.

Nowadays online converters are such a big thing that you have troubel find something even using seach words like: dcm to png offline desktop… but there are something (even if you don’t need it anymore)

and of course ImageMagic can:
