ColorWillow

ColorWillow turns photos into printable coloring pages. You upload a picture of your child, pet, family or a favourite place, choose one of four drawing styles (Classic, Anime, Kawaii or Comic), set the level of detail and whether to keep the background, and the AI converts it into clean line art ready to print and color.

Besides the AI converter, the site has a large library of free printable coloring pages sorted by theme and style, including easy pages for young children and detailed adult coloring, plus coloring books and personalised pages. There is also a batch mode for converting several photos at once.

Some tools are free and don't use AI at all: a photo-to-line-art converter that runs on your own device, a Mandala Maker with rotational and mirror symmetry, layers and colors, which exports SVG, PNG or PDF, and a pixel-art tool. These need no account or credits.

The AI photo conversion needs an account and credits. New accounts get 50 credits once, valid for 7 days, and paid plans add more.

Good fit for parents and grandparents making personalised coloring pages, teachers preparing classroom activities, party planners making custom coloring sheets, and adults who enjoy mandala and detailed coloring.
