3D thumbnail

Snapshot a PNG preview from any 3D model file.

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

Choose a 3D file

STL, STEP, IGES, OBJ, PLY, GLB, FBX, 3MF, DAE

How it works

1
Drop a model
Add any supported 3D file. Parsing is fully in-browser.
2
Frame the view
Orbit, pan and zoom until the model is composed the way you want.
3
Download the PNG
Snapshot the viewport and save the thumbnail image.

What resolution is the PNG?

The snapshot uses the viewer's current pixel size — resize your window for a larger thumbnail.

Is the background transparent?

The viewer renders on a solid neutral studio background so subjects read clearly on any page.

Which formats can I thumbnail?

STL, STEP, IGES, BREP, OBJ, PLY, GLB, glTF, FBX, 3MF and DAE — anything the CAD & 3D suite can read.

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

Parse STEP, IGES, BREP via OpenCascade WASM.

Open Wavefront .obj meshes with orbit and wireframe.

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.
