One .glb file. A WebGL canvas. No Blender.
GLB is the binary pack of glTF: mesh, PBR, images, and optional animation in a single file. This viewer reads that pack with the File API and draws it with WebGL. Use it to check a Generate download, an AR export, or a client share before you convert or print.
One drop. Orbit. Close the tab when you are done. Nothing is posted.
1
The File API reads the binary in this tab. Nothing is posted to 3DLogo.io. Keep it under 80 MB.
2
Drag to rotate, scroll to zoom, right-drag to pan. Clips play when the GLB includes them.
3
Use Convert GLB to OBJ for desktop, or Generate if you still need a new mesh.
Same Khronos scene. Different packaging. Pick GLB when you need one attachment. Keep glTF when you are editing buffers by hand.
| Topic | GLB | glTF |
|---|---|---|
| Files | One .glb | JSON plus optional .bin and images |
| Share | Email or drop as a single attachment | Easy to break if a sidecar is missing |
| Web fetch | One request | Several requests unless packed |
| This viewer | Drop the .glb | Self-contained .gltf only |
Need geometry only? Open OBJ or STL from the format menu. They will not show this PBR look. Convert toward GLB when the next step is the web.
Parsing and drawing both happen on the device. Close the tab and the object URL is gone. That is why you can inspect a client GLB you would not put on a random upload form.
Web, AR, and a single-file share. Geometry, PBR materials, textures, and clips in one binary.
Open this GLB viewer, drop the .glb, and orbit. Chrome, Firefox, Safari, and Edge with WebGL are enough. No plugin and no account.
No. The File API and WebGL both run on this device. DevTools will not show the mesh leaving the page.
The file may be a glTF folder saved with the wrong extension, or buffers were stripped. Re-export as binary GLB from the source app.
Yes. Open the GLB to OBJ converter or GLB to STL converter from this page. Still in the browser.
Yes. Opening a GLB is free. Generate still uses credits. The logo editor stays free.
Viewing is free. Generate uses credits on an account. The logo editor stays free.
