Drop a .glb file — packaged glTF with embedded textures — and pull out a printable STL.
100% local · file never leaves your browser
GLB packages a glTF scene, its meshes, textures and animations into a single binary file. It's the format of the web: AR Quick Look, Sketchfab, Babylon.js, Three.js all read it natively.
STL is geometry-only. We flatten the GLB scene graph, weld the meshes together, and write the triangles. Textures, animations and PBR materials are dropped.
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.
GLB (binary) is supported here. For .gltf with external buffers, package it into GLB first in your DCC tool.
No — STL is a static mesh format. Export the rest pose to GLB before conversion.
glTF uses Y-up by convention; some slicers expect Z-up. Use your slicer's orient button to fix it.
