An information processing apparatus includes a visibility value calculator and a color converter. The visibility value calculator is configured to calculate a value for visibility indicating a degree of easiness in viewing when document image data is output, based on a color of the document image data and a color of background image data which becomes a background when the document image data is output. The color converter is configured to convert, when the visibility value is less than a predetermined visibility tolerance, the color of the document image data so that the visibility value becomes not less than the tolerance.
