How to use

Three steps from a PNG to a printable 3D relief model.

  1. 1

    Upload an image

    Click or drag a PNG / JPG into the upload area. High-contrast images with a clear subject work best; a transparent-background PNG uses its transparent areas as the base plate automatically.

  2. 2

    Tune the parameters

    Drag the sliders to set relief height, edge bevel, base plate, contrast and edge subdivision, then pick a material and color mapping. Or apply a preset in one click: 3D Printing, Lithophane, or CNC Carving.

  3. 3

    Preview & export

    Watch the 3D relief update live on the right — drag to rotate, scroll to zoom. When you're happy, hit Export STL or Export 3MF. The file downloads straight from your browser, watermark-free and free.

Pro tips

  • For portraits and photos, convert to a high-contrast grayscale first for a crisper relief.
  • For lithophanes, choose the Translucent material with a thick base plate for softer backlighting.
  • For CNC carving, a low relief with a hard edge follows toolpaths more cleanly.
  • Slice STL in Cura / Chitubox; pick 3MF when you need color printing.
