Irfanview can do batch rename and file type changes. It might be able to do batch corrections too, I don't know, I haven't tried. ComfyUI, while it requires an internet connection to URL 127.0.0.1:8188, runs using your processor (preferably on a Nvidia gaming setup). Now ComfyUI is for generating pastiche images and for "training" images sets yourself to make targeted pastiche images, so I don't know if it can be used as image recognition software. I doubt it. I'm pretty certain you have to do the "recognizing" for it so it can copy the right stuff into a pastiche.
