OBJ viewer

Open Wavefront .obj meshes with orbit and wireframe.

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

Wavefront .obj files

How it works

1
Drop an OBJ file
Add a Wavefront .obj model. Parsing runs entirely in your browser.
2
Orbit the mesh
Rotate, pan and zoom; toggle wireframe to inspect topology.
3
Export or snapshot
Convert to STL / PLY / GLB or save a PNG preview.

Are MTL materials loaded?

The viewer uses a neutral studio material so meshes render consistently. Colours and textures from .mtl files are not applied.

Can I load quad meshes?

Yes. OBJ quads are triangulated on load so any polygonal mesh renders correctly.

Can I convert OBJ to GLB?

Yes. Load the file then export as GLB, STL or PLY from the download menu.

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

Parse STEP, IGES, BREP via OpenCascade WASM.

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

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.
