Although I have not used it for a while so not sure it is exactly that. It also does not support batches, you must run one image at a time, but that can be scripted. It also does not support multiple operations, so you might need to use the .v extensions as intermediary between multiple presets(for example sepia + resize + crop).
If I do this on my mac, I wonder if am technically violating the HEIC patent license. I suppose it depends on the details in the patent license, plus perhaps rights Apple has acquired for its users. I definitely don't know, but maybe someone on HN does?
I think converting HEIC into jpg would be simple
