GLB viewer
GLB viewer: open a model, see what is in it
Updated · Türkçe
Quick answer
Drop a .glb file to turn it around, zoom in, and read its file size, triangle count, materials, textures and animations. The file opens in this tab and is not uploaded. It is the same viewer Teleplay Studio uses for its own models, so it reads their compressed textures as well.

What the numbers tell you
| Number | Why it matters | Rule of thumb |
|---|---|---|
| File size | What a player downloads before seeing it | Web games want this small; textures are usually what makes it big |
| Triangles | How much the graphics card draws each frame | A background prop needs far fewer than a hero character |
| Meshes | Separate pieces, each with a draw cost | Fewer is usually faster |
| Materials and textures | How many surfaces it paints | Shared materials keep memory down |
| Animations | Clips stored in the file | Zero means it can't move by itself |
How to use it
1.Add the file
Drop a .glb, or choose one. To look around first, use the example model.
2.Look at it
Drag to turn it, scroll or pinch to zoom. The toolbar switches between shaded, clay and wireframe, which shows how the mesh is built.
3.Check the numbers
Compare them with what your game or engine can afford.
This viewer takes .glb only. A .gltf with separate files needs those files beside it, which a browser can't reach from a single drop.

Questions
Is my model uploaded?
No. The file is opened by this tab through a local address, and it is gone when you close the tab.
Why won't my file open?
It may be damaged, or use Draco compression, which this viewer doesn't read. Meshopt geometry and KTX2 textures do work.
Is a triangle count the same as a polygon count?
Not always. Modeling tools count quads and larger faces as polygons, while the graphics card and this viewer count triangles.
Does it work on a phone?
Yes, on a phone that supports WebGL, though a very large model can run out of memory.
Can I edit the model here?
No, it is a viewer. It doesn't change or save your file.
