The present disclosure provides a transmission method and an electronic device. The transmission method includes the steps of detecting whether a predetermined condition is satisfied; dividing the data to be transmitted into a first data and a second data when determining that the predetermined condition has been satisfied; converting the first data to a third data with a first algorithm and the second data to a fourth data with a second algorithm, so that the sum of the amounts of the third data and the fourth data is less than the sum of the amounts of the first data and the second data, wherein the first algorithm is different from the second algorithm; and transmitting the third data and the fourth data to the receiving device.
