GLB / glTF Viewer — open 3D models in your browser

Both are the same glTF format; .glb is the binary, single-file version with geometry, materials, and textures packed inside, while .gltf is JSON that often points to separate .bin and image files. A .glb almost always 'just works' here. A .gltf may load with missing textures if its companion files aren't bundled in, since the viewer reads one file at a time.

Most often the textures aren't embedded in the file — common with .gltf that references external images. It can also happen if the model uses a material feature the viewer doesn't render, or if the asset genuinely has no materials. A self-contained .glb is the most reliable way to see textures appear.

Close, but treat it as a preview, not a final proof. glTF uses physically based (PBR) materials, and the exact look depends on the lighting and environment each renderer applies. Geometry, UVs, and which textures are present will match; subtle shading, reflections, and tone-mapping can differ from your target app.

There's no fixed server limit because nothing uploads — the practical ceiling is your device's memory and your browser. Models up to a few hundred MB usually open fine on a normal laptop; very large or high-polygon scenes may load slowly or, on low-memory devices, fail to render. Closing other heavy tabs helps.

You can compare proportions visually, but this is a preview viewer, not a measurement tool. glTF is defined in meters by convention, though exporters don't always honor that — if exact dimensions matter, verify them in your modeling or game tool rather than eyeballing them here.

The file is read locally by your browser and isn't sent to any server, so the model never leaves your device during viewing. That's a property of how an in-browser viewer works — for any binding commitments about data handling, see the Privacy Policy.
