An image output apparatus includes an image output unit, a presumption unit, a comparison unit and an output control unit. The image output unit outputs, in a predetermined format, an image of a content of a document file. The presumption unit presumes a first region/language setting of a document file created environment where the document file is created. The comparison unit compares the first region/language setting with a second region/language setting of the image output apparatus. The output control unit makes the image output unit output the image of the content of the document file by using a region/language setting selected from the region/language settings, which are compared with each other by the comparison unit, on the basis of a result of the comparison by the comparison unit in accordance with a predetermined selection condition.
