Photo to Sketch & Coloring Page

How to use

  1. 1Upload a photo and choose Pencil sketch or Coloring page.
  2. 2Adjust detail and line strength, then download or print.

How it's calculated

Pencil sketch uses the classic 'color dodge' of a grayscale image with its blurred inverse. Coloring pages use Sobel edge detection with a threshold.

Frequently asked questions

Which photos make the best coloring pages?

Simple subjects with clear outlines — pets, toys, buildings — on plain backgrounds.

Can I print it?

Yes — download the PNG and print it; the white background uses no ink.

Is it AI?

No — it uses classic image-processing filters, so it's fast and private.
