Methods, systems, and apparatus, including computer programs encoded on computer storage media, for generating a floorplan user interface. One of the methods includes receiving, from a user device, a request for presentation of image content that depicts a floorplan; determining whether one or more criteria for providing image tiles instead of a vector image that depicts the floorplan are satisfied, each of the image tiles having the same tile size, having a file size that is smaller than a vector image file size for the vector image, and depicting a portion of the floorplan; and in response to determining that the one or more criteria for providing image tiles instead of a vector image that depicts the floorplan are satisfied, providing, to the user device, one or more image tiles from the image tiles to cause the user device to present the one or more image tiles on a display.
