A free, parametric dieline generator for crafters, makers and small packaging runs. Pick a template, type its dimensions, watch it fold in 3D, and export a cut file at exact 1:1 physical scale, ready for a cutting machine, a laser or a print shop.
Use it online → diecutstudio.com
No account, no watermark, nothing to install. Everything runs in your browser.
- 55+ parametric templates. Every template is a pure function
(dimensions) → dieline. Change a number and the whole net recalculates: panels, flaps, tucks, glue tabs, slots and notches. - Exact 1:1 output. All geometry is stored in PDF points (1 in = 72 pt). Print or import at 100% and a ruler agrees with what you typed.
- Live 3D fold preview. The Fold Engine derives the 3D model from the flat dieline itself, so the preview can't drift from the file you cut.
- Separate layers. Cut (blue), crease/score (red dashed), bleed (green) and glue areas are distinct layers and colours, so cutter software can map them to cut vs. score.
- Three export formats:
- PDF in native points, the exact page size
- SVG with real in/mm units, imports 1:1 into most cutter software
- DXF (R12, mm) for CAD, laser cutters and entry-level cutter software
- Sheet imposition. See how many copies fit on a cutting mat or press sheet (12×12, 12×24, Letter, A4, 13×19, SRA2…) and export a full ganged sheet with crop marks.
- Print & Cut. Drop a logo or photo onto the piece. It prints inside the cut shape, shows on the 3D preview, and exports as a combined file or as a separate print PDF + cut SVG pair.
- Inner/outer dimensions. Enter the product (cavity) size and board thickness is compensated for you.
- Private by design. Your designs and images never leave your browser.

Box styles follow public ECMA and FEFCO structural standards. See
docs/ for a deep-dive on every model: anatomy, formulas, dimension
semantics and cutting notes.
Exported files carry geometry, layer and colour. Your cutter software decides
what gets cut vs. scored. Map it by line colour (blue → cut, red → score) or
by layer (CUT / CREASE).
- SVG is the best choice for most cutter apps. It's exported at 72 DPI so it imports 1:1 even in software that ignores SVG units.
- DXF works in entry-level cutter editions and CAD/laser software.
- PDF is for printing. Always print at 100% / actual size.

Requires Node 20+.
npm install # also enables the git pre-commit hook

The build is a static SPA, so any static host works (configure an SPA fallback

src/core/models/: one pure function per template, all registered inregistry.ts.src/core/fold/: the Fold Engine. It turns the dieline's cut + crease lines into panels and a hinge graph, then a rigid-origami solver folds them using a small per-modelFoldSpec(angles + timing). Seedocs/fold-engine.md.src/export/: hand-written PDF (via pdf-lib), SVG and DXF writers, all fed from the same polylines so the three formats can't disagree.src/ui/: React editor, gallery, and three.js 3D preview.
Tech: React 18 · Vite 5 · TypeScript · three.js · pdf-lib. No backend.
