A ladder leveler features at least one linear actuator with a respective electric motor operable to drive extension and retraction of an output shaft of the actuator, a distal end of which carries a respective ground foot. Each actuator is attached or attachable to a respective side rail of the ladder in a position placing the respective foot proximate a lower end of the side rail when in a retracted position. Under operation of the actuator in an extending direction, the output shaft drives the foot downwardly past the bottom end of the side rail to effectively lengthen the bottom end of the side rail. At least one battery is mounted or mountable to said ladder and connected or connectable to said electric linear actuators to control extension and collapse thereof, and a wired/wireless control system is operable to control extension and retraction of the first and second linear actuators.
