Transform photos to coloring sketches in Freeform

Re: "How to use Freeform to transform photos to coloring sketches?"

For iPadOS 26: I don't know of any way to use Freeform for that ... it may or may not be possible.

(1) The linked Freeform article below explains what it is possible to do using images.

You can : Add images, scans, links, and other files to a Freeform board on iPad - Apple Support

(2) You might want to experiment with applying filter effects to Photos in the Photos app to see whether that may help:

More info: Edit photos and videos on iPad - Apple Support

(3) Also: There is a third-party (non-Apple) website offering a free service to turn photos into colouring pages. As I haven't used it myself, and do not know how reliable or private that is - you would use that at your own risk.
