Calculate a circular pin template and a numbered thread sequence from a photo.
Start with a good source
Add a high-contrast portrait or graphic. The subject is center-cropped to a circle.
Design and review
Set pin count, maximum thread passes and thread strength. Inspect the simulated thread preview.
Print or export
Print the pin template and sequence sheets or save the CSV. Number pins clockwise from the top and follow each pass.
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. A greedy grayscale line optimizer approximates image darkness, without recognizing faces or separating objects. 40–120 pins and up to 1,200 passes; optimization may stop earlier when no useful dark detail remains. The drawing is a simulation, not a physical tension or thread-length calculation. Resize the complete template to fit your board.
