An image processing apparatus comprising: a processor; and memory storing instructions causing the image processing apparatus to execute: acquiring target data representing a target image; performing determination for each of a plurality of target pixels forming the target data about whether or not the target pixel is an object pixel which has density equal to or higher than predetermined density; selecting first color as a conversion color for a first object pixel of object pixels, and selecting a second color as a conversion color for the second object pixel of object pixels; converting a pixel value of the first object pixel to a first value indicative of the first color, and converting a pixel value of the second object pixel to a second value indicative of the second color to generate first converted data; and outputting the first converted data.
