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

Built for SVG vectors: Outline Extrude 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. Paths are extruded locally in your browser, so your files never leave your device.
Drag in an SVG file. Convert text to outlines and keep paths closed for cleaner edges.
Outline Extrude 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.

Width (X) | Final model width, including the base. With the aspect ratio locked, the length follows the shape's proportions and does not change with Detail. | 100mm10mm – 500mm |
Length (Y) | Locked to the width by the shape's aspect ratio. Editing it rescales the width. | |

Background | By Brightness: transparent areas of a PNG are the background; opaque images are split by Threshold. Remove by Color: transparent areas plus pixels close to any picked color are removed. Keep Background: nothing is removed. By Brightness · Remove by Color · Keep Background | By Brightness |
Background Colors | Pixels close to any of these colors are removed. Add a second color for gray-and-white checkerboards or two-tone backgrounds (up to 4). | #ffffff |
Tolerance | Higher values also remove colors further from the picked ones. Raise it if a colored fringe remains or the background is uneven. | 150 – 100 |
Transparent Fill | Fill transparent areas with this color and keep the whole image. White · Black | White |
| Option | What it does | Default / range |
|---|---|---|
Threshold | Brightness cut-off (0-255) between dark and light. Higher values count more (lighter) pixels as dark; lower values keep only the darkest pixels. | 1280 – 255 |
Extrude Height | The thickness of the extruded geometry in millimeters. Controls how tall the final 3D model will be. | 101 – 100 · step 0.1 |
Edge Rounding | Rounds the top edge of the outline. The value is the radius; 0 keeps a sharp edge. | 0.50 – 5 · step 0.1 |
Rounding Segments | The number of segments used to create the bevel curve. More segments produce smoother bevels at the cost of more geometry. | 31 – 8 |
Keep Sharp Corners | Corners that turn more than this angle stay sharp and are not smoothed. Lower values keep more corners sharp. | 375 – 90 |
Detail | Controls the resolution of the generated mesh. Higher quality produces smoother surfaces but larger file sizes. | 10.1 – 2 · step 0.1 |
Base | Adds a solid base under the shape. Rectangle follows the bounding box; Follow Outline follows the shape's outline. None · Rectangle · Follow Outline · Circle | None |
Base Thickness | Thickness of the base under the shape. | 2mm0.5mm – 10mm · step 0.1mm |
Base Margin | How far the base extends beyond the shape on each side. | 3mm0mm – 20mm · step 0.1mm |
Base Segments | Smoothness of the circular base and of rounded corners on the outline base. More segments are smoother but make a larger file. | 6416 – 256 |
Base Color | Only for 3MF export: color of the base part. | #e1e1e1 |
Extract | Choose whether the dark or the light parts of the image become solid. Pick Light Parts when the subject is lighter than the background. Dark Parts · Light Parts | Dark Parts |
| Option | What it does | Default / range |
|---|---|---|
Max Colors | Maximum number of colors kept after merging similar shades. Each color becomes its own shape, which affects how the model is split (STL too) and the parts of a multi-color 3MF. | 121 – 16 |
Ignore Small Specks | Spots and holes smaller than this area are ignored. Raise it for noisy scans; lower it to keep tiny details. | 150 – 200 |
Outline Simplification | Higher values give simpler edges and fewer triangles; 0 (default) follows the image exactly. | 00 – 4 · step 0.05 |

|---|---|---|
Relief Height | The maximum height of the raised areas in millimeters. Controls the overall relief depth. | 50.5 – 20 · step 0.1 |
Minimum Base Thickness | Thickness at the lowest point of the relief; thicker is sturdier. In By Brightness mode, transparent areas of a PNG count as background and sit at this thickness. | 10 – 5 · step 0.1 |
Smoothing | Applies smoothing to the heightmap surface to reduce noise and stair-stepping artifacts. Higher values produce smoother surfaces. | 20 – 10 |
Detail | Controls the detail level of the generated mesh. Higher resolution preserves more image detail but increases file size. | 400100 – 400 · step 50 |
Cut Out Subject | Background areas are left out: only the subject is printed, with sides following its outline. Turn off to keep the full rectangular base. | on |
Raise By | Dark Raised suits black-and-white logos and photo reliefs; Light Raised is the opposite; Vivid Raised lifts colorful areas while white, gray and black stay flat; Custom per Color sets a height for each color. Dark Raised · Light Raised · Vivid Raised · Custom per Color | Dark Raised |
Color Heights | Set a height for each main color. Pixels use the closest color. | |
Edge Rounding | Rounds the top edge of the subject's sides; 0 keeps a sharp edge. The outline grows outward by about the radius. | 0.50 – 3 · step 0.1 |
Bottom Rounding | Rounds the bottom edge of the subject's sides; 0 keeps a sharp edge (default). The footprint stays on the outline; the upper shape grows outward by about the radius. | 00 – 3 · step 0.1 |
Rounding Segments | More segments give a smoother curve. | 31 – 10 |
SVG is a vector format, so Outline Extrude 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.
Outline Extrude 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.
