Design an A4 lantern with photo or shape windows, fold lines and an assembly guide.
Start with a good source
Choose decorative shapes or add a photo for silhouette windows. Enter a printed title.
Design and review
Inspect the cut-and-fold template and assembly guide. Adjust threshold and bridges for a photo.
Print or export
Download the A4 PDF, print at Actual size and verify the 50 mm calibration line before cutting.
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 template has four 38 mm panels and a side glue tab, with a 115 mm overall height. Print on A4 at 100%, not Fit to page. Names are printed headings, not cut-out lettering. Solid lines are cuts and dashed lines are folds. Inspect photo windows before cutting. Use a battery LED only, with the top open; this is not a candle-flame enclosure.
