Thanks for bringing this up @d07RiV. It's something I've thought about as well but never got to.
It's unfortunate... some obj's do store a normal map in the bump map channel. We would need to read the colors to confirm whether the image is a normal map or bump map and convert accordingly.
In OBJ materials, bump maps represent a heightmap (gray texture).
Instead of converting them into normal maps, this tool copies them as-is, which is incorrect.
