What is a GLB viewer?

A GLB viewer is a tool that opens .glb files, the single-file binary form of glTF 2.0 that holds a mesh with its PBR materials and textures. Kenerate's free GLB viewer runs in your browser with three.js: orbit the model, switch to clay or wireframe, and read its triangle and mesh counts. Nothing is uploaded.

Why this tool

See a GLB the way it was authored

glTF was designed for real-time display, so a browser is its natural home. This viewer shows the textures first, then lets you strip them away.

  • A toy astronaut figure turning on a display turntable

    Materials as authored

    Base colour, metal-roughness, normal and emissive maps from the file are applied, under a neutral studio light with tone mapping.

    Try it
  • A brass compass model, half wireframe and half textured

    Strip it to the mesh

    Clay and wireframe show whether an AI model or asset has clean geometry under a convincing texture — the thing that matters for printing and rigging.

Also

What else it does

  • Compressed files open

    Draco and Meshopt-compressed GLBs, common on the web and from optimisation tools, decode in the page.

  • Counts that matter

    Triangles, vertices, mesh and material counts tell you if an asset fits a web, mobile or game budget.

  • Quick AR copy

    Save the same model as USDZ for AR Quick Look on iPhone and iPad.

  • Ready for print

    Save as STL or 3MF, scaled to a size in millimetres and turned Z-up for slicers.

How it works

How the GLB viewer renders a file

The same glTF loader used by thousands of three.js sites, running entirely in your tab.

  • Unpack

    The GLB container is split into its JSON scene description and binary buffer, textures included.

  • Decode

    Draco or Meshopt compressed meshes are decoded by WebAssembly decoders on your device.

  • Materials

    PBR textures are applied in sRGB with ACES tone mapping and a soft studio light rig.

  • Inspect

    Orbit, switch shading, read the stats, screenshot or convert.

How to

How to use the GLB Viewer

Time needed
Steps
4 steps

  1. Step 1

    Open the GLB

    Drag the .glb onto the box above or click to choose it. Or try the sample astronaut made with Tripo H3.1.

  2. Step 2

    Orbit around it

    Drag to rotate, scroll or pinch to zoom, right-drag to pan.

  3. Step 3

    Inspect the mesh

    Switch between Textured, Clay, Wire and Normals and read the triangle count.

  4. Step 4

    Export if needed

    Pick STL, 3MF, OBJ or USDZ and download — or take a PNG screenshot.

FAQ

GLB Viewer questions

What is a GLB file?

GLB is the binary, single-file form of glTF 2.0, the Khronos Group's format for real-time 3D. It holds meshes, PBR materials, textures and animation in one file.

Link to this answer

Can I open a .gltf file here?

Upload the .glb version. A .gltf is a JSON file that usually points to separate .bin and texture files, which a single-file upload can't include.

Link to this answer

Is my GLB uploaded?

No. It's read and rendered in your browser. Only the sample model comes from our server.

Link to this answer

Does it support Draco compression?

Yes. Draco and Meshopt compressed GLB files are decoded on your device.

Link to this answer

Why does my model look darker or brighter than in Blender?

Lighting and tone mapping differ between viewers. Use Clay mode to judge the shape, and Textured for a fair impression of the materials.

Link to this answer

Does the viewer play animations?

Not yet — the model is shown in its rest pose. Exports also contain the static mesh only.

Link to this answer

Can I convert GLB to STL here?

Yes. Choose STL or 3MF, optionally set the size in millimetres and Z-up, and download. Colour and textures are dropped because STL can't hold them.

Link to this answer

Can Blender open GLB files?

Yes. Blender imports GLB with File → Import → glTF 2.0 (.glb/.gltf), keeping meshes, PBR materials, textures and animation. Open it in this viewer first if you just want to check what's inside without starting Blender — the triangle count tells you whether to decimate it.

Link to this answer

Where can I get GLB models?

Most AI 3D generators output GLB. The Kenerate 3D Studio makes GLB models from text or photos on any paid plan or credit pack.

Why GLB became the default for AI and web 3D

glTF 2.0, released by the Khronos Group in June 2017, was designed to be loaded straight onto the GPU with little processing [4]. GLB packs the JSON, buffers and textures into one binary file [8].

That makes it easy to send, cache and display, which is why AI 3D engines, model-viewer and most web engines use it first.
