This image processing utility will generate a "posterized" abstraction of your digital photograph by reducing the gradual variations in color to a small number of discrete colors. Simply specify an image file to upload (in JPEG format), select the desired number of colors to reduce the photo to, and click on the "Generate" button to generate and display a posterized version of the source photo. Note that for efficiency reasons, the sketch image will be output in PNG format.
You may also specify RGB color adjustments to apply to the final result. Each adjustment value may be in the range [-255, 255].
