Open Tracepen Online (free, no install) →
Tracepen is a free online image vectorizer that turns a raster image (PNG, JPG, WebP) into clean vectors in your browser – export SVG, PNG, PDF, or DXF (Lines, Hatch, Faces) for Figma, Cricut, Lightburn, CNC, AutoCAD, SketchUp, or Blender. A deterministic tracer (no AI). Free with every feature: unlimited colours, every format, 2 exports a day — try it without an account and sign in (free) to download. Tracepen Pro removes the daily limit: $60 one-time, and the same purchase covers the SketchUp plugin and the Blender add-on.

Free Online Vectorizer Features
- Many export formats – SVG (Figma, Illustrator, Inkscape), PNG, PDF, DXF Lines (Cricut, Lightburn cut, CNC), DXF Hatch (Lightburn fill), DXF Faces (SketchUp, Blender, Rhino).
- Auto photo / graphic detection – suggests a colour count; slide from 2 (black & white) up to the maximum.
- Per-layer editing – toggle visibility, change a layer’s hex, adjust stroke / noise filter / minimum region size.
- Deterministic – Wu colour quantization (OKLab) → Mumford-Shah merge → contour trace → Potrace Bezier fit. Same image in, same SVG out.
- Private by design – every trace, free or Pro, runs entirely in your browser (WebAssembly); the image never leaves your machine.
Install
Nothing to install – it runs in any modern browser. Trace first; a free 3dshouse account is only needed to download the result. Tracepen Pro ($60 one-time) removes the daily export limit. One purchase covers every surface — web app, SketchUp plugin and Blender add-on.
Requirements
- Any modern browser (Chrome, Edge, Firefox, Safari).
Export formats — which to use
| Format | Best for |
|---|---|
| SVG | Figma, Illustrator, Canva, CorelDRAW, Inkscape, Affinity Designer, web |
| PNG | Any tool without SVG support (Photoshop, PowerPoint, Keynote, Word) |
| Print layout, vector in slide decks | |
| DXF Lines (closed LWPOLYLINE) | Cricut, Silhouette, Lightburn (Cut), AutoCAD, Fusion 360, LibreCAD, CNC, vinyl cutting |
| DXF Hatch (solid HATCH) | Lightburn (Fill / Scan engrave), AutoCAD visual import |
| DXF Faces (3DFACE triangulated) | SketchUp, Blender, 3ds Max, Rhino, Cinema 4D — enable Merge Coplanar Faces on import |
Each region exports as a closed LWPOLYLINE, not a stack of line segments — so Lightburn and CorelDRAW treat it as fillable immediately, with no Edit → Close Path step to repair open contours (the failure most hand-traced or text-derived DXFs hit before they can be filled or offset).
How Tracepen compares
| Tool | Type | Pricing | Runs where | DXF for CNC / laser |
|---|---|---|---|---|
| Tracepen | Deterministic trace | Free · one-time Pro | Browser + SketchUp plugin | ✔ Lines + Hatch + Faces |
| Illustrator Image Trace | Deterministic trace | Subscription | Desktop | via export |
| CorelDRAW PowerTRACE | Deterministic trace | One-time | Desktop | via export |
| Inkscape Trace Bitmap | Potrace | Free | Desktop | via extension |
| Vector Magic | Deterministic trace | Subscription | Desktop + web | ✘ |
| Vectorizer.AI | AI | Subscription | Web | ✔ (outline only) |
Tracepen is the only free, browser-based, deterministic tracer that exports DXF Lines (for cutters) and DXF Faces (for 3D) out of the box — plus a native SketchUp plugin.
Import into your tool
- Figma / Illustrator / Canva / Inkscape / Affinity — drag-and-drop the SVG, or File → Open / Import. No conversion.
- Cricut Design Space / Silhouette Studio — upload the DXF Lines export; each colour becomes a separate cuttable layer. Use Lines, not Hatch — cutters follow outlines. Heads-up: Design Space accepts DXF only on desktop — the iOS and Android apps reject it, so upload from a computer (or fall back to SVG, which works everywhere).
- Lightburn — DXF Lines for cutting (outlines → Cut mode), DXF Hatch for engraving (filled regions → Fill / Scan).
- AutoCAD / Fusion 360 / LibreCAD — DXF Lines for outlines, DXF Hatch for filled regions; every colour becomes its own CAD layer.
- SketchUp / Blender / Rhino / 3ds Max — DXF Faces, then enable Merge Coplanar Faces on import. Without that option each colour region arrives as a raw triangle fan with every diagonal showing; the merge dissolves the shared edges back into one flat face per region — but only works because Tracepen keeps each region perfectly planar, so a single Push/Pull then extrudes the whole shape. Prefer native faces? Use the SketchUp plugin instead — no DXF round-trip.
FAQ
What does the free online vectorizer tier include?
Every feature: unlimited colours, every export format, unlimited tracing and previewing. A free 3dshouse account downloads 2 results a day – enough for occasional logo, laser-cut and Cricut work.
What does Pro unlock?
Unlimited exports (the free plan allows 2 a day), on the web app, the SketchUp plugin and the Blender add-on. Nothing else differs: free and Pro trace with the same engine at full colour. $60 one-time, via Tracepen Pro.
Does it use AI?
No – a deterministic tracer, reliable for production (laser cutting, CNC, print). Because the pipeline is fixed, re-tracing the same file after a tool update gives a byte-identical result — handy when a cut file has to match an earlier production run exactly.
Is my image uploaded?
No. Every trace, free or Pro, runs entirely in your browser (WebAssembly) — the image never leaves your machine. Only sign-in and the Pro check contact 3dshouse.com.
What image format should I upload?
PNG is best for flat artwork, logos, screenshots and icons. JPG works for photos — raise the Noise filter to 3–6 to clean JPEG artefacts before tracing. One thing JPG cannot carry is transparency: flatten or matte your subject onto a solid colour first, since a traced JPG always fills the whole frame whereas a PNG with an alpha channel keeps the background empty.
How does Tracepen compare to Vector Magic, Vectorizer.AI or Adobe Image Trace for DXF and CNC use?
Tracepen is the only free, browser-based, deterministic tracer that exports DXF Lines and DXF Faces for CNC, laser and 3D out of the box — see the comparison table above.
