How to open a GLTF file
- Click Open GLTF Viewer.
- Drag & drop your
.gltffile into the viewer. - Rotate, zoom, and inspect materials and scene objects.
Tip: A .gltf file often references external .bin data and texture images. If something is missing, upload the whole folder (GLTF + BIN + textures) or use GLB for a single-file version.
What is a GLTF file?
GLTF (GL Transmission Format) is a modern 3D format designed for efficient delivery and rendering of 3D scenes on the web. It commonly supports meshes, PBR materials, textures, cameras, lights, and animations (depending on the asset).
GLTF tips for best results
Many GLTF assets use external
.bin + texture files. If your model loads without textures, make sure you included all referenced files.
GLTF uses PBR workflows (baseColor/metallicRoughness/normal). If materials look flat, check that all maps are exported and correctly referenced.
For easiest sharing and uploading, export to
.glb (single binary file). It’s usually faster and avoids missing-file issues.

FAQ
Is this GLTF viewer free?
Yes — you can open and preview GLTF files directly in your browser for free.
Why are textures missing in my GLTF file?
Many .gltf files reference external textures (and a .bin file). Upload all related files together, or export as .glb to package everything into one file.
What’s the difference between GLTF and GLB?
.gltf is typically a JSON scene file that may reference external .bin and textures. .glb is a single binary file that usually bundles the scene + data + textures.
Can GLTF include animation?
Yes. GLTF can include animations (and sometimes skinning/rigs), depending on how the asset was exported.
Can I share a link to the GLTF viewer?
Yes. Share the viewer URL after loading a model, or link to /3d-viewer?format=gltf.
