The embodiments of the disclosure provide a screenshot capturing method, an electronic device and a computer-readable medium. The method includes operations as follows. A duration of a pressing operation is obtained, in response to detecting the pressing operation. In response to determining the duration reaches a preset duration, a page currently displayed on the touch screen is determined as a specified page, and a selection box is displayed on the display screen. A sliding operation acting on the touch screen is obtained. One side of the selection box is controlled to move with the sliding operation, and a position of an opposite side of the selection box is controlled to remain unchanged. In response to determining the sliding operation ends, a screenshot mode is entered based on a positional relationship between an end point of the sliding operation and the specified page, so as to capture a screenshot image.
