How to color a page with AI

Open any page in the free library and choose Color with AI, pick one of your own creations, or upload a coloring page or line art drawing.

02Styles
Six color styles
- Crayon
- Playful crayon texture, like a page colored by hand.
- Marker
- Bright, bold colors with clean even fills.
- Watercolor
- Soft washes of color with gentle edges.
- Pastel
- Light, calm colors for a gentle look.
- Storybook
- Warm picture-book colors that feel cozy.
- Realistic
- Natural colors with soft pencil shading.
A colored version is a quick way to try color ideas before you pick up your own crayons or pencils, to show a child what a finished page can look like, or to make a bright picture for a card or a screen. Clean, closed outlines give the most even color; very busy or sketchy drawings can come back with a few areas colored differently than you expect.
03Privacy
Your pages stay private
The page you color and the colored result are kept in private storage that only your account can open, and they are never added to the public library. Only upload drawings you have the right to use, and keep it family-friendly: see the Acceptable Use Policy and the Privacy Policy. Need a page to color first? Browse the free coloring page library, describe one to the AI coloring page generator or turn a photo into a coloring page.
04FAQ
AI colorizer questions
How many credits does coloring a page cost?
Each colored page uses two credits. Credits are reserved when you submit and only charged when the colored page is ready, so a page that cannot be colored does not use any credits. New accounts get six free credits, enough for three colored pages.
Which pages can I color?
Any page in our free coloring page library (open a page and choose Color with AI), any coloring page you made with our generator or photo tool, or your own line art. Uploads can be JPG, PNG or WebP files up to 10 MB and at least 256 pixels on the shorter side. Only upload drawings you made or have the right to use.
Will the AI change my drawing?
The AI is told to keep every outline where it is and only add color. Each result is compared with your page before you see it, and a result that moved or lost outlines is not delivered and uses no credits. Some styles add a little texture or a soft shadow under the subject.
Which AI model colors the page?
Pages are colored by Google’s Nano Banana 2 (Gemini 3.1 Flash Image) model through our image provider APIMart. Your page and every colored result are also checked by an automated content filter.
What do I get?
A colored PNG, about 900 by 1200 pixels for a portrait page, saved privately in My Creations. It works well on screen, as a color reference while you color the printed page, or printed at a small size.
