How to Use the 3D File Viewer

Inspect 3D models online on desktop, tablet, or phone. Open GLB or GLTF, then rotate, zoom, and pan to check geometry, materials, and proportions before importing into Unity, Unreal, or Blender. No extra software needed.

  1. Open a GLB or GLTF — drag onto the drop zone or click Open 3D File to browse. The file is read locally in your browser and never uploaded to any server.
  2. Inspect in 360° — drag to orbit, scroll to zoom, right-click drag to pan. Auto-rotate gives you a hands-free full spin.
  3. Convert first if needed — OBJ, STL, FBX, PLY, and 3MF go through the 3D File Converter to GLB, then open the result here.

What is an online 3D file viewer?

A 3D file viewer loads a model in the browser so you can inspect geometry and materials without installing Blender or a game engine. This tool opens GLB and GLTF — the standard formats for web 3D, AR, and real-time engines. Your file is read locally and never sent to a server.

Which formats can I view? OBJ, STL, FBX?

Open GLB and GLTF directly. For OBJ, STL, FBX, PLY, or 3MF, first convert to GLB with the 3D file converter, then view the result here. That covers the same workflow as a multi-format viewer without any desktop app.

Can I inspect the model in detail?

Yes. Orbit, zoom, and pan to check geometry, proportions, and surface detail from every angle before importing into Unity, Unreal, or Blender. Auto-rotate gives a quick 360° overview. The viewer supports PBR materials, environment lighting, and shadows.

Is the 3D viewer free and private?

Yes. Preview is free and needs no account or install. Your GLB/GLTF is read locally in the page and is never uploaded to any server, so your models remain completely private. Use it to check assets from Image to 3D or Text to 3D before sharing.
