Outputs in Bitcoin transactions specify the recipients and the amount of bitcoin being transferred. Each output creates a new unspent transaction output (UTXO), which can be used as an input in future transactions. Any leftover value can be sent to a change address or used for fees, ensuring precise fund allocation.
