How to open a GLB file
- Click Open GLB Viewer.
- Drag & drop your
.glbfile into the viewer. - Rotate, zoom, and inspect materials, objects, and animations (if included).
Tip: GLB is the easiest way to share GLTF assets because it bundles geometry, materials, and textures into one file.
What is a GLB file?
GLB is the binary form of GLTF (GL Transmission Format). It packages the full 3D scene—geometry, materials, textures, and other data—into a single file for efficient loading and easy sharing.
GLB tips for best results
Use GLB when you want a single file that includes textures and scene data—great for web previews and sending to clients.
Large textures increase GLB size quickly. Resize textures and use compression when possible for faster loading.
GLB can include animation clips, rigs, and skinning (depending on export). If animations don’t play, verify they were exported.

FAQ
Is this GLB viewer free?
Yes — you can open and preview GLB files directly in your browser for free.
What’s the difference between GLB and GLTF?
.glb is a single binary file that usually bundles everything (scene + textures). .gltf is often a JSON file that may reference external .bin and texture images.
Why is GLB recommended for sharing?
Because it reduces missing-file issues—textures and geometry are commonly packaged into one file, making it easier to upload and send.
Can GLB include animation?
Yes. GLB can include animations (and sometimes rigs/skinning), depending on the export settings.
Can I share a link to the GLB viewer?
Yes. Share the viewer URL after loading a model, or link to /3d-viewer?format=glb.
