A medical image display system includes a server, and a medical image display terminal that communicates with the server. The server includes a storage that stores medical image data in a storage format, and a first transmitter that transmits the medical image data in the storage format to the medical image display terminal. The medical image display terminal includes a first hardware processor that converts the medical image data in the storage format transmitted from the server into medical image data in a viewing format that is viewable on a web browser, and a display that displays a medical image based on the medical image data in the viewing format on the web browser.
