Extrude an SVG into STL

Extrude supported filled SVG contours into STL. Set width and depth, preview locally and preserve supported holes; text and curved paths require preparation.

Supported input and output

SVG rect, circle, ellipse, polygon and closed straight M/L/H/V/Z paths → binary STL. Output centered in X/Y, base at Z=0.

Filled contours become a mesh with thickness

Supported filled shapes and closed straight paths are triangulated, including accepted compound-path holes, then extruded to the chosen depth. Nested transforms are applied before scaling the geometry to the selected width. The result is centered in X/Y with its base at Z=0; SVG page dimensions do not independently set print size.

How to use this tool

Prepare filled geometry: supported shapes or closed straight M/L/H/V/Z paths.
Choose the SVG, set output width and extrusion depth, and review the hole/fill preview.
Export STL and confirm the chosen coordinate units when opening it for printing.

Limitations to check

Even-odd and nonzero compound-path fill rules and holes are supported. Nested matrix/translate/scale/rotate transforms are applied.
Circles and ellipses use 64 segments. Curved paths, rounded rectangles, strokes, text, CSS, effects and references are rejected. Convert to simple filled line paths first.
Intersecting/touching contours and overlapping separate shapes are rejected. Separate disjoint shapes remain separate shells.
Root viewBox/width/height do not define physical output: chosen width scales the geometry bounds. Scripts, handlers, DTDs and external assets are never executed or fetched.

File and processing limits

SVG input up to 256 KiB, 256 elements and 16 nesting levels.
At most 1,024 flattened points/path segments and 32 KiB per path; circles/ellipses use 64 segments.
20 seconds per job; 150,000 vertices, 50,000 triangles and 3 MiB output.

Processing happens in this browser; your file and filename are not uploaded. Cancel, reset or replace the file to stop its worker. Downloads are generated locally.

Questions about this workflow

Can I extrude text, strokes or curved path commands?

Those constructs are rejected. Convert text and strokes to filled contours in a vector editor and flatten curves into supported straight segments. Circles and ellipses are accepted separately and approximated with 64 segments.
