For a cleaner result
Start with less visual noise.
Portraits, pets, and everyday objects work well. Look for soft daylight, clear edges, and contrast between the subject and background. Skip motion blur and deep shadows.

FAQ
Photo to coloring page — common questions
Is this AI segmentation?
No. Outline & Play uses classical edge detection in your browser (grayscale, blur, Sobel-style edges, threshold). Busy photos may need a clearer source image.
Do you upload my photos?
No. Processing stays on-device. See Privacy for host log details on this vercel.app preview.
Why only five downloads per day?
A small local counter in your browser discourages bulk scraping of the demo. Clearing site data resets it.
