The embodiments of the present invention provide an information-duplication system, an information duplication method, an electronic device, and a machine-readable storage medium. First, a selection region is determined according to a duplication operation of a user on the display content of an electronic device. Then, the text information corresponding to the selection region is converted into pictures. Finally, the pictures converted from the text information in the selection region are merged with the pictures in the selection region, and the picture generated after merging is then shared as a duplication content. The embodiments of the present invention can realize the simultaneous presence of text information and pictures in the duplication content.
