How to Open GLB Files in Sketchfab
Sketchfab is the largest platform for publishing and embedding 3D models on the web, with its own viewer and store.
Short answer · Built in
Yes. Sketchfab opens GLB files as shipped: Upload (top bar), then choose the .glb.
Import GLB into Sketchfab, step by step
- 1Check the fileA GLB is self-contained: geometry, materials and textures are inside the one file, so there is nothing else to copy.
- 2Import into SketchfabUpload (top bar), then choose the .glb.
- 3Check scale and orientationSketchfab works in any (the viewer frames the model) and is Y-up or Z-up (set in the 3D settings editor). GLB files are metres by convention, so they normally arrive at the right size.
- 4Check materials and animationGLB carries PBR materials and embedded textures and can carry animation. Look at the model under a neutral light before you build on it.
What comes through

Things to watch for
- GLB is the cleanest upload: materials and textures are found automatically.
- After uploading, open Edit 3D Settings to fix orientation, lighting and materials before publishing.
