Coloring pages and line art are made by our AI provider, fal.ai, which processes your photo under its own terms; we send it with fal's request storage turned off. Outlines are traced on our servers without AI. We delete your photo from our storage once the page is made (24 hours at most), and results after 7 days or right away with Delete now. Privacy

How it works

    Upload

    A photo with a clear subject and a plain background works best.

  2. 2

    Choose edge detail

    Simple keeps only strong edges; Detailed traces more.

  3. 3

    Download

    A print-ready 300 DPI PNG, or a PDF sized for US Letter or A4.

How the outline is made

The outline tool uses edge detection. It follows the contrast in your photo, so it does not change the geometry of the subject. That makes it a good starting point for stencils, crafts and cutting-machine projects. It also means busy backgrounds add extra lines — crop close or use a plain background for the cleanest result.

Frequently asked questions

Is the outline redrawn by AI?

No. The outline tool traces edges that are already in your photo, so shapes stay the same. Because no AI is involved, outlines don't use your AI pages and your photo is never sent to an AI provider. For a simplified, redrawn page, use the coloring page tool.

Can I get an SVG?

Not yet. Outlines download as a print-ready 300 DPI PNG or as a PDF today.

What happens if a page fails?

If a page can't be made for a technical reason, the page it used is returned automatically. In a coloring book, only the failed page is returned — the others are kept.

What happens to my photo?

Your photo stays in your browser until you click Generate. For coloring pages and line art it is then sent to our AI provider, fal.ai, which makes the drawing. We send it with fal's request storage turned off, so it isn't kept in fal's request history, but fal processes it under its own terms and privacy policy. Outlines are traced on our own servers and never go to an AI provider. We delete the photo from our storage right after the page is ready (24 hours at most). Results are deleted after 7 days, or when you click Delete now.

One page is free. A whole book is better.
