glTF / GLB viewer

Preview .glb and .gltf 3D assets in your browser.

Runs entirely in your browser. Files never leave your device.

Choose a 3D file

.glb / .gltf (self-contained)

How it works

1
Drop a .glb or .gltf
Add the model file. Assets are loaded fully in your browser.
2
Inspect
Orbit around the model and toggle wireframe if needed.
3
Export
Download the same geometry as STL, OBJ, PLY or GLB.

Are .glb and .gltf both supported?

Yes. Binary .glb files load directly; text .gltf files are supported when they embed buffers/textures as data URIs.

Does it decode Draco or Meshopt compression?

Basic glTF geometry loads without extra setup. Draco / Meshopt-compressed assets are not yet decoded.

Can I re-export as STL for 3D printing?

Yes. Load the glTF, then export STL, OBJ or PLY for slicing.

Open .stl models — orbit, wireframe, snapshot, convert.

Parse STEP, IGES, BREP via OpenCascade WASM.

Open Wavefront .obj meshes with orbit and wireframe.

Convert between STL, STEP, IGES, OBJ, PLY, GLB, FBX, 3MF, DAE.

Reduce triangle count with meshoptimizer — lighter STL / GLB.

Snapshot a PNG preview from any 3D model file.
