Image to STL Converter

Turn flat graphics into 3D-printable STL files. Upload PNG, JPG, WEBP, or SVG — we extrude clean outlines (Logo) or sculpt a heightmap from photos (Relief).

Conversion runs on a temporary worker service to keep this page fast. Treat uploads as transient and avoid sensitive files.

What are you converting?

Pick Logo for vector-like artwork (SVG recommended) or Image to sculpt depth from a photo.

PNG / SVG to STL conversion preview — sample output

How it works

  1. Pick Logo (for vectors/signs — SVG recommended) or Image (for photos).
  2. Upload your PNG, JPG, WEBP, or SVG.
  3. Set width and/or height (mm) plus thickness, then download.

Use cases

  • Logos, icons, and simple silhouettes
  • Name plates, signs, and badges
  • Stamps and maker project labels
  • Photo reliefs and lithophanes from JPG/PNG

Tips for cleaner STL output

  • SVG usually produces cleaner geometry than PNG.
  • For Logo: use high-contrast graphics (simple shapes, not photos).
  • For Image: start on Balanced quality, bump to High only if details are missed.
  • If the Image result looks inverted, toggle "Invert heights".
  • If your slicer asks for units, choose millimeters (mm).

About

This PNG/SVG to STL converter turns a flat graphic into a simple 3D model by extruding it into thickness. Upload a PNG or SVG, set your target size in millimeters, choose a thickness, and download a ready‑to‑slice STL. It’s a practical workflow for signs, badges, name plates, stamps, and maker projects—not a tool for sculpted, photo‑realistic 3D models.

Sizing is intentionally simple: thickness is required, and you can enter a width and/or height in mm. If you provide only one dimension, the other is derived to preserve aspect ratio. If you provide both, the tool preserves aspect ratio by default and fits the shape inside your width × height box.

SVG usually produces cleaner geometry because it starts as vector paths. PNG is traced from contours, so very noisy images (especially photos, gradients, or blurry edges) can produce rough borders in the resulting STL. For the best results, use high‑contrast artwork with clear silhouettes and simplified shapes.

Tip for printability: keep small details above your printer’s effective resolution. If thin features disappear in a slicer preview, increase the overall size or simplify the graphic. Since STL does not embed units, most slicers assume millimeters—this tool outputs sizes in mm.

Privacy note: conversion is performed by a temporary conversion worker so the main app does not do heavy STL generation. Treat uploads as transient and avoid sensitive files. If a conversion fails, you can retry with the same settings.

If your slicer reports non‑manifold edges or missing faces, try an SVG version of the same artwork (or simplify the PNG), increase thickness slightly, and re‑export. Simple, vector‑like inputs usually produce the most reliable watertight meshes.

How it works

  1. 1Open Image to STL Converter and choose your file or enter the required input.
  2. 2Check the settings and start the process.
  3. 3The tool creates the result with temporary server-side processing.
  4. 4Download the output or copy the result when it is ready.

FAQ

›What files are supported?
PNG (.png) and SVG (.svg) are supported. For best results, use high‑contrast shapes and clean edges.
›Is PNG or SVG better for STL?
SVG is usually better because vectors convert to cleaner outlines. PNG is traced from pixels and can produce rough edges for noisy images.
›Do I need both width and height?
No. Enter at least one. If you enter only width or only height, the other dimension is derived to preserve aspect ratio.
›What thickness should I use?
For signs and badges, 1–3 mm is a common starting range. Increase thickness for stiffness and durability.
›Can I use this for logos and signs?
Yes—this tool is best for flat graphics like logos, icons, and silhouettes that you want to extrude into a printable plate.
›Why does my PNG produce rough edges?
Low resolution, compression artifacts, gradients, and blurry edges make tracing noisy. Use a higher‑contrast image or switch to SVG.
›Is my file stored?
Conversion is handled by a temporary worker service. Treat uploads as transient; avoid sensitive files.
›Why won’t my STL open in a slicer?
Try re‑exporting with a cleaner SVG/PNG, increasing thickness, and importing again. Some slicers are strict about mesh validity—vector‑like inputs tend to work best.
