A GLB file is the binary form of glTF, a modern 3D format designed for the web and real-time graphics. It packs the model’s geometry, materials and textures into a single self-contained file, which makes it ideal for sharing and for opening in a viewer like this one.

What is the difference between GLB and glTF?

They are the same format in two containers. A .gltf file is JSON text that often references separate files for binary data and textures, while a .glb file bundles everything into one binary file. GLB is more convenient to share because there is only one file to move around.

How do I move the camera around?

Drag with the left mouse button to orbit around the model, scroll (or pinch) to zoom in and out, and drag with the right mouse button to pan. The Reset button reframes the model if you lose it, and Spin rotates it for you.

Is my model uploaded anywhere?

No. The file is opened and rendered entirely in your browser, on your own device. It is never sent to a server, so even large or confidential models stay private. There is no sign-up and no queue.

GLB Viewer

Open and inspect .glb models in your browser. Drag in a GLB file to rotate, zoom and pan, switch to wireframe, read its size and triangle count, and save a screenshot. The file opens locally and is never uploaded.

How to use it

1
Open your model

Drag a file onto the viewer or click Open model. It loads straight from your device, with nothing uploaded.
2
Orbit, zoom and pan

Drag to rotate, scroll to zoom, and right-drag to pan. Turn on Spin to rotate it automatically, or Wireframe to see the mesh.
3
Inspect and capture

Read the triangle count, vertex count and dimensions in the info bar, then save a PNG screenshot of the current view.

When it comes in handy

Preview game and web assets

GLB is the standard for the web and game engines, check an asset looks right before you import it.

Verify an export

Confirm a GLB you exported has the geometry and scale you expected.

Screenshot for a listing

Frame the model and grab a PNG for a marketplace listing or a portfolio.

Opens locally & 100% in your browser

Your model is read and rendered right here on your device. The file is never uploaded to a server, there is no sign-up and no size limit beyond what your browser can handle, and any screenshot you save is generated locally too.
