miners get them to incentive them to put your tx in a block.
and its to prevent tx spam

Transaction fees are optional for transactions. These goes to the miners which includes them into a block and thus recording it as a ledger. This works both as a way to counter transaction spams and to give an incentive for miners to mine. Transaction spam can be a prominent issue and transaction fees works as a way for miners to select transactions by proritizing them by the order of fees paid. This makes network spam operations more expensive. Mining reward drops from 50 Bitcoins, halving every 4 years and around 2140, the block reward would pretty much be gone. Transaction fees would be the only incentive then.

Some wallets like multibit hd takes additional fees for their development costs.
