Question 1

How does the coloring page generator work?

Accepted Answer

Upload any photo and the tool uses edge detection algorithms to convert it into a black-and-white line drawing suitable for coloring. All processing happens in your browser.

Can I adjust the line thickness?

Can I print the coloring pages?
