Turn SVG vectors into printable STL: extrude logos, stamps, and nameplates, or make shallow reliefs, free online.

Built for SVG vectors: contour mode extrudes closed paths into uniform-thickness solids, ideal for stamps, logos, and nameplates. Filled artwork with light and dark areas works well with heightmap mode for shallow relief. For best results, convert text to outlines and keep the paths closed. Everything is processed locally in your browser, so your files never leave your device.
Original SVG
Contour extrusion
Heightmap relief
DefaultContour
Select how the image should be converted into 3D geometry.
Generates solid shapes with uniform thickness from image outlines. Ideal for stamps, logos, nameplates, and other uniform-thickness objects.
Creates a relief surface based on image brightness, so brighter areas are raised and darker areas are recessed. Perfect for photo reliefs, terrain models, and artistic surfaces.
DefaultOff
Swap which parts of the image become solid and which become empty. Useful when the background is lighter than the subject.
Default128
Range0 – 255
Controls the brightness cut-off point that determines which pixels become solid geometry. Lower values include more pixels as solid; higher values only include the darkest areas.
Default10
Range1 – 100
The thickness of the extruded geometry in millimeters. Controls how tall the final 3D model will be.
Default0.5
Range0 – 5 · step 0.1
Adds rounded edges to the contour shape for a smoother, more polished finish. Higher values create more rounded edges.
Default3
Range1 – 8
The number of segments used to create the bevel curve. More segments produce smoother bevels at the cost of more geometry.
Default0.8
Range0 – 1 · step 0.1
Preserves sharp corners and fine details by controlling the angle threshold. Lower values protect more detail; higher values smooth more aggressively.
Default1
Range0.1 – 2 · step 0.1
Controls the resolution of the generated mesh. Higher quality produces smoother surfaces but larger file sizes.
Default5
Range0.5 – 20 · step 0.5
The maximum height of the raised areas in millimeters. Controls the overall relief depth.
Default1
Range0 – 5 · step 0.5
The thickness of the flat base plate beneath the relief. A thicker base provides more stability for printing.
Default2
Range0 – 10
Applies smoothing to the heightmap surface to reduce noise and stair-stepping artifacts. Higher values produce smoother surfaces.
Default400
Range100 – 400 · step 50
Controls the detail level of the generated mesh. Higher resolution preserves more image detail but increases file size.
DefaultOff
Swap the height mapping, so brighter areas become recessed and darker areas become raised.
Drag in an SVG file. Convert text to outlines and keep paths closed for cleaner edges.
Contour mode extrudes closed paths into uniform-thickness solids for stamps and nameplates. Heightmap mode turns shaded fills into a shallow relief.
Fine-tune settings such as bevel, then download the STL and slice it directly for printing.
SVG is a vector format, so contour mode extrudes the outlines into geometry with crisp, sharp edges, which is ideal for logos and stamps. PNG and JPG are pixel-based, so they work best in heightmap mode for photo reliefs or lithophanes. Complex illustrated SVGs can also be tried in heightmap mode.
Contour mode extrudes closed outlines into solid geometry. Open curves and stroked lines often fail to create a usable solid, or they produce fragile thin walls. Before converting, close all paths, convert strokes to fills, and merge any loose or overlapping shapes in your vector editor.
No. STL stores geometry only, not color. The tool generates a single-color solid based on the path outlines, or on brightness in heightmap mode. If you need color, use SVG to 3MF or paint the print afterward.
Yes. Extruded contour solids usually slice cleanly in Cura, PrusaSlicer, Bambu Studio, and similar slicers. Check the thickness and bevels first, since very fine features may need thickening. For reliefs, verify the base thickness and the minimum wall thickness.
Convert the text to outlines in your design tool so each letter becomes a filled shape that can be extruded. Use a bold, simple typeface and keep the letters large enough to print. Thin serifs and very small text may break or produce fragile walls.
Bevel rounds the sharp edge between the top face and the sides of the extruded solid, removing fragile corners and improving print quality. A small bevel around 0.5 to 1 mm is usually enough; larger values make the silhouette softer.
