How it works

  1. Add a photograph. A clear subject against a plain background works best.
  2. Leave the lines bold and the background white: that is what a colouring page needs.
  3. If the result is too busy, try a photo with less detail — a portrait rather than a crowd.
  4. Download and print it — or set “Save as” to “Coloring page PDF (A4)” or “Coloring page PDF (US Letter)” to get a page ready to print.

Frequently asked questions

What kind of photograph works?
One with clear edges and an uncluttered background: a face, a pet, a car, a building. A busy scene turns into a mass of small lines that is no fun to colour.
Why are there grey speckles in the sky?
Gentle gradients have no edges to find, so the tracing picks up noise instead. A bolder line setting or a photograph with a plainer background clears it up.
How do I print it at A4?
Set “Save as” to “Coloring page PDF (A4)” (or US Letter): the drawing is centred on the page, as large as fits inside a 12.7 mm (½ in) margin, and the page turns landscape when the photo is wider than tall. To put several on one sheet, download the PNGs and use the photo print layout.
Is my photograph uploaded?
No. It is processed in your browser, which matters when it is a photograph of your family.
