Sketch Generator

( <-- Back to Image Processing )

This image processing utility will generate a "sketch"-like abstraction of your digital photograph. Simply specify an image file to upload (in JPEG format), set the desired sketch parameters, and click on the "Generate sketch" button to generate and display the source photo's sketch image. Note that for efficiency reasons, the sketch image will be output in PNG format.

For best results, use crisp, high resolution source images.
