A radiographic imaging apparatus includes a radiation detector, a reader and a hardware processor. The radiation detector includes a substrate. On the substrate, radiation detection elements are arranged two-dimensionally. The radiation detection elements generate amounts of electric charges corresponding to doses of radiation by being irradiated with the doses of the radiation. The reader reads the amounts of the electric charges generated by the respective radiation detection elements as signal values, and generates image data based on the signal values. The hardware processor communicates with a portable terminal having a web browser, generates web content displayable on the web browser in response to a request from the portable terminal, and sends at least one of the web content and the image data to the portable terminal in response to the request from the portable terminal.
