How to Turn Your Photos into Colouring Pages

Photo-to-line-art is one of the most requested features in digital colouring ecosystems.

Clean conversion workflow

1. Start with high-contrast source photos.
2. Remove noisy backgrounds first.
3. Detect edges and simplify contour noise.
4. Close open lines manually for better fill behavior.
5. Export at 2048 x 2048 for modern tablet quality.

When your outlines are bold and fully enclosed, both digital fill and printable colouring work much better.
