Select a local file from the upload area. The page checks the file type and size before processing.
Free GLB Inspector
Read the actual GLB JSON chunk locally and check structure, estimated geometry, materials, textures, skins, and extensions before handoff.
Browser-only, private
Inspect GLB and glTF metadata locally before Blender, Unity, Unreal, or client handoff.
Quick tips
- A valid 12-byte GLB header is not enough; this inspector parses and validates the JSON chunk boundaries too.
- Estimated triangle counts come from primitive accessors and should be confirmed after decoding compressed geometry.
About Free GLB Inspector

Frequently asked questions
What is Free GLB Inspector?
Read the actual GLB JSON chunk locally and check structure, estimated geometry, materials, textures, skins, and extensions before handoff.
Is Free GLB Inspector free?
Yes. This browser tool is free to use and does not add watermarks to exported files.
Are my files uploaded?
No for these browser utilities. The supported processing path runs locally in your browser session.
What file size works best?
Smaller files finish faster. Very large images, videos, or 3D meshes may be limited by browser memory and device performance.
Will the output keep every detail?
Output quality depends on the source file, browser capability, and what the target workflow can represent.
Do I need to install software?
No. Use the page directly in a current browser, then download the processed result.
