Create symbol charts, suggested thread colors and detailed printable sections.
Start with a good source
Add a photo. Set grid detail and the maximum number of colors.
Design and review
Switch between symbol and color charts. Inspect the full pattern, enlarged sections and thread key.
Print or export
Save the PDF and inventory CSV; compare suggested thread colors with physical skeins.
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. Suggested DMC codes are nearest matches in a curated 24-color subset, not the complete manufacturer catalog or an official color guarantee. Pattern counts are stitches, not skein quantities. The chart uses full stitches only. Enlargement sections have row/column ranges for assembly.
