SVG to STL Converter

Yes, with no watermark and no file limit. Everything runs in your browser, so the file never leaves your computer; a free account is needed only to download a converted file. Viewing needs no account at all.

No. The file is opened by JavaScript running in your browser tab and never sent to a server. You can disconnect from the internet after the page loads and the tool keeps working. That is the main reason to prefer this over an upload-and-email converter for a drawing you are not allowed to share.

From the file. If the SVG declares a physical width or height (Inkscape writes width="210mm"), the viewBox is mapped onto it and the drawing comes out at that size. If it only has pixel dimensions, the CSS convention of 96 pixels per inch applies, so a 960 px wide SVG becomes 254 mm. The size is shown after the file opens, and on the STL pages you can override it.

Paths (all commands, including arcs and relative coordinates), rectangles with and without rounded corners, circles, ellipses, lines, polylines, polygons, text as a label, and <use> references, with every nested transform applied. Groups become layers. Gradients, filters, masks, clip paths and embedded images have no geometry and are skipped; text is not outlined, so convert text to paths in your editor first if you need it cut.

An STL is a closed solid, and only a closed outline can bound one. Artwork that is drawn as strokes rather than shapes — a signature, an outlined sketch, a line drawing exported straight from a pen tool — has a thickness on screen but no inside, so there is nothing to extrude and those paths are skipped and counted. The fix is in your editor: Path → Stroke to Path in Inkscape, or Object → Expand in Illustrator, turns each stroke into a real outline with two sides. A filled shape does not need this even if its path never ends in Z, because a fill closes the outline by definition.

By nesting. A closed outline inside another closed outline is a hole; an outline inside a hole is solid again, so the counter of a letter O and the island inside it both come out right. The mesh is built so every edge is shared by exactly two triangles, which is what a slicer needs to tell inside from outside. The exception, since it is easier to hear it here than to find out in the slicer: two holes that overlap each other — a bore with a keyway cut into it, say — are cut as two holes rather than merged, and the surface where they cross is left open. Draw that pair as one shape and it closes.

The drawing's real size by default, taken from the SVG's own units, so a 100 mm plate prints at 100 mm. You can instead set the longest side, which scales the whole model. Thickness is the extrusion height. An STL carries no units, and every slicer assumes millimetres, so that is what is written.

No, and for an SVG that is the point. An AI generator guesses at a shape it cannot see and hands back a mesh that approximates your artwork. An SVG already contains the exact outline, so there is nothing to guess: the same coordinates you drew become the wall of the solid, edge for edge. A circle stays round, a 40 mm square stays 40 mm, and running the file twice gives you the identical mesh. That makes this the right tool for a logo, a badge, a stencil, a gasket or a nameplate, and the wrong one for turning a photograph of an object into a model of the object.

Yes, by several routes, and they are worth knowing. Tinkercad imports an SVG and lets you set the height, which is fine for one shape but asks you to sign in and works in its own units. Recent Bambu Studio and Orca Slicer can drop an SVG straight onto the plate as a part, which is the fastest path if you only ever print it there and never need the file itself. Inkscape is not an exporter here — it is where you fix a file first, by turning strokes into paths and text into outlines. This page exists for the case those leave out: you want the STL itself, at a size you set in millimetres, without an account, and without the file leaving your machine.

Not in an STL, and no tool can: the format stores triangles and nothing else — no colour, no materials, no names. Colour areas that sit side by side do come through as separate solids in the same mesh, correctly placed, so you can assign filaments to them in your slicer. One caveat worth knowing before you print: a shape that sits entirely inside another is read as a hole rather than as a second body, because that is what nesting means for an outline — it is what makes the counter of a letter O come out right, and it is not what you want if you meant the inner colour as a raised inlay. Split those into two files and print them as two parts.

Anything in the file that is a picture rather than a shape: embedded or linked raster images, gradients, filters, masks and clip paths. Text stays text — it is carried as a label, not outlined — so convert it to paths in your editor if it has to be cut or printed. Whatever was skipped is listed under the preview after the file opens, by element type and count, so nothing disappears silently.

Yes. The converter on every one of these pages accepts DXF, DWG and SVG, whichever page you started from, and offers every output it can produce from that file.

Not for this tool yet. The converter runs entirely client-side. The REST API, command line tool and MCP server currently cover image to DXF, DWG and STL; if you need vector conversion in a pipeline, say so at the contact page and it moves up the list.
