Portable air conditioners are surprisingly good at removing moisture from the air as a byproduct of the cooling process, but many portable ACs also have a specific dehumidification function.
It is recommend buying portable ACs with a reasonable dehumidification function if you live in a humid area. It's not vital in milder conditions but can make your home more comfortable.
Almost every portable AC has a dehumidification function, usually as part of '3 in 1 functionality (fan, cooling, dehumidifying).
ACs remove some moisture during normal operation, but in dehumidification mode, the compressor runs with a slower fan speed, extracting more moisture from the air.
