Both "needless" and "unnecessary" refer to something that is not required or not essential. They imply that something could be avoided or omitted without loss or detriment.
The word "needless" often has a slightly stronger connotation of wastefulness or lack of sense, suggesting that something is glaringly not needed or is pointless. "Unnecessary", while similar, is a more neutral term and may not carry the same connotation of waste. "Needless" can sometimes imply more of a critique or judgment about the lack of necessity.
