Project overview
The short version
ColorWillow offers free coloring PDFs, a photo-to-outline tool and optional AI generation. Print the public library in A4 or US Letter without an account. The free photo tool is described as processing on your device, but saving a converted result to the site uploads it. AI generation requires sign-in and credits; its photo workflow also uploads original images. Private AI results have different usage rights from public-library artwork.
