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.

Is my glTF file uploaded when I open it?

No. The .gltf or .glb is read and rendered on your own device and never sent to a server, so nothing you open is stored or shared. There is no account to create and no upload step.

What size does it report for the model?

The info bar shows the bounding-box width, height and depth in the file's own units, for example 1.8 x 0.9 x 0.4. Use it to confirm the model is the scale you expect before you import it into an engine or scene.

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.

View a glTF model online the way a browser or engine will render it, without importing it into anything first. This free glTF viewer opens a .gltf or .glb file on your device so you can rotate, zoom, pan and toggle wireframe. It reports the bounding-box size and triangle count, and lets you save a screenshot of the framed view. The file stays in your browser and is never sent to a server.

How to use it

1
Load a glTF or GLB

Drop a .gltf or .glb file onto the page, or click Open model. It renders on your device with no upload.
2
Orbit the scene

Left-drag to orbit, scroll to zoom in and out, right-drag to pan. Use Spin for a hands-free rotation or Wireframe to see the mesh.
3
Inspect and save

Read the bounding-box size and triangle count, then save a PNG of the framed 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 reads 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.
