Convert STL to SVG Online

Convert an STL 3D model to an SVG directly in your browser — a free STL to SVG converter with no upload and no install. Preview the geometry, then download an SVG containing a rendered, shaded snapshot of your model.

Note: this SVG embeds a rendered snapshot image rather than true vector line art — see the FAQ below for why that's the honest approach for real 3D meshes.

Frequently Asked Questions

How do I convert an STL file to SVG?

Drop your .stl file into the STL to SVG converter above, preview the model, then click Convert to SVG and download the file. It renders a shaded snapshot of your model and wraps it as an SVG — free, and entirely in your browser.

Can you convert STL to SVG?

Yes — this tool converts an STL model into an SVG file containing a rendered, lit snapshot of the geometry. See the next question for what that means in practice, since it isn't traditional line-art vector geometry.

What does this SVG contain?

A rendered snapshot of the model — a lit, shaded 3D view captured as an image — embedded inside the SVG file, using the same camera angle, lighting, and material as this app's live model preview.

Is this real vector artwork?

No. The SVG file wraps a single embedded raster image (a PNG), not vector lines or shapes. It was built this way deliberately: a true vector render with correct solid shading and hidden-surface removal isn't reliably possible for detailed, non-convex meshes — real STL models — with the technique that's actually feasible in a browser.

Why isn't this a real vector conversion, like this app's other converters?

Correct hidden-surface removal on an arbitrarily complex 3D mesh needs per-pixel depth testing, which is fundamentally a raster technique. Drawing sorted triangles as vector shapes instead breaks down on concave or detailed geometry — verified directly, it produces a jumbled, incorrect result on real models rather than a clean line drawing.

Can I edit the shapes in Illustrator or Inkscape?

Not meaningfully — there's no real vector geometry to edit, just an embedded picture. If you need true editable vector geometry, this isn't the right output for that.

Can I choose a different viewing angle or lighting?

Not currently — the render always uses the same default angle and lighting as this app's live model preview.

Is my STL file uploaded to a server?

No. The conversion happens entirely in your browser. Your file is never sent to our servers.
