Free GLB Inspector
Check GLB and glTF model structure locally before import, review, or handoff.
Inspect GLB and glTF metadata locally before Blender, Unity, Unreal, or client handoff.
About this tool: Free GLB Inspector
Inspect GLB and glTF headers, size, scene, mesh, material, and animation counts locally before 3D handoff. No upload required — everything runs locally in your browser for privacy and speed.
Common use cases
- Check GLB and glTF model structure locally before import, review, or handoff.
- Check model files, texture dimensions, and real-world scale before 3D generation, import, or delivery.
What a GLB inspector tells you
The render a generator shows you is a camera angle; the GLB is what you ship. The inspector reads the file itself — triangle count, bounding box, materials and textures — which is how you catch a wrong scale or a missing texture before anyone else does.
Reading a model before you ship it
- 1
Start with the bounding box
Compare the longest edge against the real object. A factor of a thousand is a metres-versus-millimetres export; a squashed axis is a broken transform.
- 2
Check that textures actually attached
A GLB can carry geometry with no image data. Zero materials renders as grey; materials with no images render black.
- 3
Judge the triangle count
Tens of thousands is healthy for one object. Millions will stall a viewer or an engine; a few hundred means detail was lost.
GLB inspector questions
- What does an inspector show that a viewer does not?
- Numbers. The viewer answers "does it look right", the inspector answers "what is it made of" — triangle count, bounding box, materials and textures.
- Can I inspect without uploading the file?
- Yes. The file is parsed in your browser, so a client model never leaves your machine.
- Does inspecting cost credits?
- No. Local tools are free; credits only apply to generating new models.
