CryLater

What it does

A fully client-side editor that turns a reference photo into a tattoo transfer stencil without using AI, through pure pixel processing. It has three stencil engines (global threshold, adaptive threshold, Sobel edge), brush/eraser/selection/rectangle/ellipse/line retouching tools, layer opacity control, a millimeter A4-A3 layout grid and a 300 DPI print output flow. Work and preferences are saved to localStorage automatically and restored even after the page is reloaded. Free to use; no account or server needed.
