Drop a .jpg photo — portrait, landscape, anything — and turn it into a printable relief.
Lighter pixels are pushed higher (relief). Drag to adjust.

JPG → STL extrudes each pixel by its luminance: bright pixels become peaks, dark pixels stay flat. The output is a watertight 3D solid ready for any slicer.
For lithophanes, increase contrast in your photo editor first — soft gradients flatten the relief. For carved-look reliefs, boost shadows and use a thicker base.
The file is parsed in WebAssembly + WebGL on your device. Nothing leaves.
No queue, no upload. Most files convert in well under a second.
Orbit, pan and zoom the result in real time before you commit.
High contrast, clear subject, no busy background. Black-and-white portraits work brilliantly.
Slightly. JPG noise becomes surface texture. Use PNG when you can.
Yes — the solid is watertight. Print with vase mode or thin walls for lithophane-style transparency.
