glTF (GL Transmission Format) is an open standard for 3D scenes and models, often called "the JPEG of 3D". It is built for efficient loading in browsers, games and AR, and is the most widely supported modern 3D format on the web.

Can it open a .gltf that references other files?

This viewer works best with self-contained files: a .glb, or a .gltf that embeds its data and textures. A plain .gltf that points to separate .bin and image files needs those companions too, which a single-file drop cannot provide, in that case, export or convert to .glb first.

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.

glTF Viewer

View .gltf and .glb models in your browser. Drag in a glTF file to rotate, zoom and pan, toggle wireframe, see its dimensions and triangle count, and take a screenshot. It opens on your device, with nothing 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

Check web 3D content

glTF is the format behind most web and AR 3D, preview it the way a browser or engine will.

Inspect materials

See how a model’s materials read under even lighting before integrating it.

Confirm scale

Read the bounding-box size to check the model is the dimensions you expect.

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.
