Bold, simple pictures work best. Photos with lots of detail turn to mush at 40 cells. You can frame the part you want after choosing.
Drag the frame to move it, its corners or edges to resize it, or drag on the picture to frame a new area. With a keyboard, Tab to the frame: arrows move it, Shift + arrows resize it, and adding Alt takes bigger steps.
Your pictures and settings stay in this browser on this device, so you can come back to them. Nothing is uploaded.
What you get
Every picture becomes a page: a grid with a number in each cell and a legend of numbered colours to match. The book PDF starts with a cover, then a page per picture, then the finished pictures small at the back, to peek at. Print at 100% on Letter or A4. Cells print about 5 mm wide at 40 cells across.
