Convert STL to SVG (Free)
Also converts OBJ, GLB, PLY, USDZ, 3MF, WRL from the same file.
Runs in your browser. No upload, no signup, nothing to install.
Also from Innerscene: Circadian Lab, a free lighting calculator for room illuminance, melanopic EML, and glare.
How to convert STL to SVG
- 1
Open your .stl file
Drag it onto the viewer above, or click "Open an STL File". Files up to 200 MB open directly; the parse runs in a worker so the page stays responsive.
- 2
Pick Scalable Vector Graphics in the Export menu
Click Export in the toolbar, then SVG (.svg).
- 3
Download
The .svg is written in the browser and saved straight to your downloads folder. No queue, no email, no watermark.
What survives the conversion
A file conversion is a translation, and formats do not carry the same things. Here is exactly what moves from STL into SVG, and what does not.
| Geometry | Reduced | The 3-D model is projected to the current view and written as 2-D paths, with hidden lines removed. It becomes a drawing, not a model. |
|---|---|---|
| Colors and materials | N/A | STL files carry no color, so the SVG comes out in the viewer’s default material. You can color it in the destination application. |
| Units and scale | Dropped | SVG stores no unit. Coordinates are written in meters, so set the import unit to meters if the destination asks. |
What the SVG writer emits: From a 3-D model: the same visibility pass as the vector PDF, written as SVG paths, with hidden lines clipped. From a drawing: a direct translation of the line work, keeping strokes, fills, gradients, dash patterns, clipping and live text.
The source: Stereolithography (.stl)
A single triangle soup. STL stores no color, no units, no parts and no layers, only the surface.
The target: Scalable Vector Graphics (.svg)
Resolution-independent vector art for web pages, documents and further editing.
Opens in: Illustrator, Inkscape, Figma, any browser.
Your file never leaves your computer
Both the STL parser and the SVG writer are JavaScript and WebAssembly running in your own browser tab. There is no upload step, no server-side conversion queue, and no copy of your file anywhere but your machine. That matters for drawings under NDA, for client work, and for anything you would not email to a stranger.
Frequently asked questions
▶Is this STL to SVG converter free?
Yes. No signup, no watermark, no per-file limit and no paid tier. Innerscene.
▶Is my STL file uploaded anywhere?
No. The file is read with the browser file API and converted in the same tab. Nothing is sent to a server unless you explicitly click Share, which is a separate, opt-in feature.
▶Will my colors and materials survive the SVG export?
STL files carry no color, so the SVG comes out in the viewer’s default material. You can color it in the destination application.
▶Will the SVG open at the right size?
SVG stores no unit. Coordinates are written in meters, so set the import unit to meters if the destination asks.
▶How large an STL file can I convert?
Up to 200 MB, and the ceiling adapts to how much memory your device reports. The conversion runs on your own hardware, so a desktop with plenty of RAM will handle more than a phone.
▶Can I convert SVG back to STL?
Not here. We read STL and write SVG, but not the reverse. the universal 3D viewer
▶Which browsers does it work in?
Chrome, Edge, Firefox and Safari, on Windows, macOS, Linux, iOS and Android. No plugin and no extension.
