Online GLB & glTF Viewer
Drop a .glb or .gltf file to open it in a fast 3D viewer — drag to rotate, scroll to zoom, and inspect the model. Free, instant, and 100% local: your file never leaves the browser.
No GLB handy?
About the GLB viewer
- Got a .glb file and nothing that opens it? This page is the whole answer — no app, no account, no upload.
- This is the fallback a lot of people land on after Windows 11 dropped the built-in 3D Viewer app that used to preview .glb files. An online GLB viewer needs no install and no admin rights, so it also works on locked-down work machines.
- Views GLB and glTF 2.0 — the standard format for web, AR and asset pipelines. Self-contained .glb files load most reliably.
- Everything runs on your device with WebGL. There's no upload, no account, and no file-size paywall.
- A single .gltf that references external .bin or texture files may render geometry only, since those side files aren't included in one upload — .glb bundles everything and is preferred.
- Need it for printing or editing? Convert the GLB to STL, OBJ or 3MF below.
Frequently asked questions
- How do I open a GLB or glTF file online?
- Drop your .glb or .gltf file into the box above. It opens instantly in a 3D viewer — drag to rotate, scroll to zoom. Nothing is uploaded; the file is read locally in your browser.
- What program opens a .glb file?
- You don't need one — this page opens .glb files directly in the browser. On the desktop, Windows 3D Viewer, Blender and most game engines import GLB too, but they all require an install; this doesn't.
- Does Windows 10 or 11 have a built-in 3D viewer for .glb files?
- Windows 10 shipped a 3D Viewer app that previewed .glb and .fbx, but Microsoft removed it from the default Windows 11 install, so a fresh Windows 11 machine has nothing that opens a .glb. You can still install 3D Viewer from the Microsoft Store, or just drop the file into this page — no install, no admin rights needed.
- Can I view a whole folder of .glb files at once?
- Not in one go — this viewer opens one model at a time so it can render at full quality without loading everything into memory. For a quick pass over a folder, open each file in turn; each one loads in about a second because there is no upload step.
- Why won't my .glb file open by double-clicking it?
- GLB isn't registered to an app on most systems, so double-clicking does nothing or opens a text editor. Drag the file into the box above instead and it renders immediately.
- What's the difference between GLB and glTF here?
- GLB is the binary, self-contained version of glTF — geometry, materials and textures in one file. A .gltf is JSON that often points to separate .bin and image files. Both open here; .glb is the most reliable because everything is bundled.
- Is this GLB viewer free?
- Yes. It's completely free with no signup, no watermark, and no file-size limit beyond 200MB. The model renders locally with WebGL.
- Is my GLB file uploaded anywhere?
- No. There is no server and no upload. The file is parsed and rendered entirely on your device, and nothing is stored.
- Can I convert the GLB to STL for printing?
- Yes. Flip3D converts GLB to STL, OBJ, 3MF and PLY in the browser. The convert links are next to and below the viewer.
