Turn any photo into a 3D printable lithophane. Dark areas print thicker, bright areas thinner — hold the print up to a light and the image appears. Perfect for gifts, night lights, and window art.
Upload a photo, tune the size and thickness, then generate and download a print-ready STL.

Portraits, pets, landscapes — the tool converts brightness to thickness automatically, with adjustable contrast via thickness range.
Thin areas pass more light than thick ones, revealing the photo in smooth grayscale when lit from behind.
Optional full-thickness border keeps the plate rigid and gives you a clean edge for mounting in stands or night lights.
A lithophane is a 3D print whose thickness varies with image brightness: dark pixels become thick material that blocks light, bright pixels become thin material that glows. This generator converts your photo to a heightmap plate STL you can print on any FDM or resin printer.
