I have a broken air conditioner that plugs into my 220V USA wall

prongs. Before next summer I'd like to buy a 120V portable room air
conditioner. Is there a converter available that would allow me to
safely plug the 120V 3-prong socket portable air conditioner into the
220V outlet? Thanks.

Why not buy a 240v unit so you don't have to rework/run new wires?

I'm having trouble finding a 220v "portable" air conditioner that's
designed and priced for a bedroom-sized area. I was hoping there would
be a converter box available that could make my American 120v appliance
compatible with my American 220v socket.

As said, a transformer for 220-to-120V would be the size of an AC & the
price (or more)! Relatives in the UK had one so they could use a
favorite American vacuum cleaner (Filter Queen). It was a big as the vacuum.

By "portable" A/C do you mean free-standing, or a window-mounted, unit ?
how many BTUs are you looking for ?

Is there no standard 120 volt outlet nearby ? Even if a heavy duty
extension cord is needed ?
