Convert an image to a printable STL
Built for 3D printing: brightness becomes height, and the result is a solid model with a flat base and walls, ready to slice. Choose a raised relief for signs and coasters, or a lithophane that reveals the photo when lit from behind.

How it works
Three steps, no software to install.
- 1
Upload an image
High-contrast pictures and logos give the crispest relief.
- 2
Choose relief or lithophane
Relief: bright areas rise. Inverted: dark areas rise. Lithophane: dark areas are thicker so light passes through the bright parts.

Tips for better results
- For lithophanes, print in white PLA, standing upright, with 100% infill.
- Increase contrast before uploading; flat images make flat reliefs.
- Use a transparent PNG to keep only the logo raised and the rest at base height.
- Higher detail means larger STL files; 180 is a good default.

questions.
Is the STL watertight?
The model is a closed solid: a height-mapped top, a flat bottom and four side walls. Some slicers report the shared edges as separate shells; that is harmless and fixed by any repair pass.
How thick is a lithophane?
Brightest pixels get the thinnest material and darkest pixels the thickest. At the default 100 mm width that runs from about 0.8 mm to 3.8 mm; scaling the model in your slicer scales thickness too.
Can I make a full 3D object instead of a relief?
Yes. Use the AI reconstruction engine on the Image to 3D page to infer the full shape of an object from a photo.
