Image Heightmap to STL

Image to STL Converter Online Free

Turn an image into a simple STL heightmap model. Bright areas become raised geometry, darker areas stay lower, and the result downloads as an STL file.

This is useful for quick relief-style models, logo experiments, texture-to-surface tests, and early 3D printing ideas.

How Image to STL Works

The converter samples your image, turns brightness into height, adds a base, and exports the result as an STL mesh.

  1. Upload an image such as PNG, JPG, JPEG, or WebP.
  2. Choose mesh resolution and height scale.
  3. Generate the STL heightmap in your browser.
  4. Download the STL and review it in your slicer or modeling tool.

FAQs

Quick answers for image to STL conversion.

Is this a true 3D model from an image?

It creates a heightmap relief model, not a fully reconstructed 3D object.

Which images work best?

High contrast images, logos, icons, and grayscale heightmaps usually produce cleaner STL surfaces.

Can I 3D print the STL?

You can test it in a slicer, but thin details and steep relief may need cleanup before printing.
