Input
PNG image
A raster image. Pixel brightness is read as relief height.
PNG to STL converter
Turn a PNG image into a printable STL model right in your browser: height map relief, watertight solid, ready to slice. No upload, no software to install.
Output
Stereolithography
The 3D printing format: triangles only, no colour, UV or hierarchy. Every slicer understands it.
- Pixel brightness becomes relief height. Transparent areas are treated as background.
- STL stores triangles only, so colour, textures and UV coordinates are not carried over.
- The object hierarchy collapses into one solid mesh — that is what the format requires.
- The model is rotated Z-up automatically, the way slicers expect it.
