Private web-asset inspector

Free Online GLB Viewer

Open a .glb asset directly on this device to inspect its scene, geometry and materials before publishing it on the web, sharing it or converting it.

Try a local GLB sample

Choose a classic model to test the viewer before opening your own file.

Sample models from the public common-3d-test-models repository.

What this GLB viewer checks

GLB is the binary container form of glTF. It commonly packages JSON scene data, geometry buffers, materials and images into one portable file, making it practical for web viewers, product previews, AR handoff and asset delivery.

  1. 01 Choose or drop a .glb file.
  2. 02 Let the local glTF loader build its scene and materials.
  3. 03 Rotate, zoom and inspect mesh, vertex and face counts.

GLB compatibility

Feature Status What to expect
Embedded mesh geometry Supported Vertices, indices and scene transforms render locally
Embedded materials and textures Supported Standard glTF resources remain inside the file
Multiple mesh nodes Supported Scene placement is preserved
Animation clips Not played Use a dedicated animation viewer for playback
Draco, Meshopt or KTX2 Decoder dependent Compressed extensions may not load in this viewer
External resource links Blocked Outside network requests are prevented

Private local processing

The browser reads the selected bytes and sends them straight to the local parser and 3D renderer. There is no model upload endpoint, account, storage bucket or server-side processing step.

Limits to know

Static geometry and supported materials render, but animation clips are not played. Draco, Meshopt, KTX2 and application-specific extensions that need extra decoders may not load. GLB files that still point to external resources are rejected to preserve private local processing.

Convert or inspect another format

GLB to OBJ Extract GLB mesh geometry into a simple editable format. GLB to glTF Export the binary asset into JSON-based glTF.

Frequently asked questions

Is my GLB file uploaded?

No. The GLB is parsed and rendered locally on your device.

Will GLB materials and textures appear?

Standard embedded glTF materials and images can appear. Assets that require unsupported compression decoders or application-specific extensions may not match the source tool.

Does this viewer play GLB animations?

No. It displays the loaded scene for geometry inspection but does not provide an animation timeline or clip playback.

Can I convert GLB to OBJ or glTF?

Yes. The related converters create OBJ or glTF output locally in the same browser workflow.
