Print both sheets or download dot coordinates as CSV.
Privacy and practical limits
Everything is generated on your device; photos, names and designs are not uploaded. No AI model or cloud processing is used. JPG, PNG and WebP: up to 20 MB and 16 MP per photo, 50 MB combined, four photos for a book and one for other tools. Photos are normalized to a 640-pixel working copy; complex textures and low contrast may need different settings. SVG and PNG export the selected sheet; PDF includes every sheet, including separate solutions. PDF artwork is rasterized at approximately 200 dpi on A4. SVG contains vector shapes/text and embedded pixels for photo puzzles; original metadata is not retained. Smaller inputs may be needed on mobile. Cancel stops the active worker; changing controls discards stale results. The largest dark connected region supplies the outer contour. This is silhouette thresholding, not object recognition; dark backgrounds can produce a rectangular outline. Dot labels can become crowded at high difficulty. The completed outline is included separately.
