Description
I frequently find myself dealing with PNGs that should have been JPGs instead. It would be very helpful if ImageOptim would have additional logic that would compare a certain percentage compression (we could set it to 85% or 90% or higher quality) and if there is a 10% or more savings in size then changing or copying a file to a JPG from PNG should be performed.
I think that most of us would agree that such a savings with a high quality JPG output would be a worthwhile exchange and it happens for some of us frequently enough that it would be useful to have.

Research direction
Start by reviewing ImageOptim's existing PNG optimization and JPG conversion behavior. Define the quality and savings thresholds, whether the PNG should be replaced or copied, and verify that qualifying PNGs produce the intended JPG without affecting other images.
