How It Works
Upload Image
Any photo, logo, or sketch. PNG, JPG or WEBP.
Pen Sketch
Edge detection converts it to a clean line drawing.
FFT
The contour path is decomposed into frequency components.
Epicycles
250 rotating circles animate and reconstruct the shape.

Not satisfied with our sketch?
Our auto-sketch works best on simple shapes and logos. For portraits, detailed artwork, or photographs, you can use a free AI image generator to create a clean coloring-book outline instead.
Convert the uploaded portrait into a clean black-and-white coloring-book style line-art illustration. Requirements: ā¢ White background only ā¢ Black outlines only ā¢ No shading ā¢ No grayscale ā¢ No hatching ā¢ No pencil texture ā¢ No skin texture ā¢ No wrinkles ā¢ No pores ā¢ No photographic details ā¢ Smooth vector-like curves ā¢ Preserve facial features ā¢ Preserve hairstyle ā¢ Preserve clothing outline ā¢ Suitable for children's coloring books ā¢ High contrast ā¢ Large continuous contours ā¢ Minimal internal detail ā¢ SVG-friendly line structure ā¢ Output as clean line art only The result should look like professional coloring-book artwork rather than an edge-detected photograph.
Once you have a clean line-art image, click ā Cancel above, then re-upload the AI-generated sketch on the main page.
