Build your own folding diagrams with paper shapes, valley and mountain folds, arrows and notes. Export numbered instruction sheets.
Create your design
Choose a starting style and adjust its real dimensions, content or artwork. Add a photo when requested.
Keep the preview beside the controls. Use Expand for precise touch drawing or dragging, and Undo/Redo for design changes.
Review every sheet or frame. Export the artwork, or save an editable project to continue later.
Capabilities and limits
A manual diagram editor, not an origami solver or folding simulator. Up to twelve steps with editable paper shapes, fold lines, arrows and notes. Use Expand for touch dragging.
Save, print and share
Everything is generated locally. No uploads, AI model calls, external artwork, remote fonts or account connections. SVG text uses device fonts; PNG/PDF preserve the rendered appearance. Save a project to continue later; refreshing clears unsaved work. Images: PNG/JPG/WebP up to 12 MB and 16 MP, processed at at most 1024 pixels on the longest edge. Editable projects are limited to 8 MB. Print at 100% and check the calibration line before cutting. PDF contains raster artwork at the selected resolution; choose SVG for vector cutting or editing.
