How to view a .GLB file online
Three steps, no software to install.
Choose your file
Drag your .GLB file onto the box above. If it comes with companion files like .mtl, .bin or textures, drop them together with it.
It opens right away
Your .GLB file is opened and shown in 3D.
Inspect and measure
Rotate, switch views, toggle wireframe and check size, area and volume before printing.
What is a .GLB file?
Meshes, scenes and what "watertight" means for 3D printing.
A GLB file is a 3D model in glTF 2.0 Binary format, one self-contained file with geometry, materials, textures, and animation. On Windows open it free with Microsoft 3D Viewer; on macOS press Space in Finder (Quick Look); in any browser drag it into gltf-viewer.donmccurdy.com. The format is safe to open from reputable sources.

Is my .GLB file uploaded to your server?
No. Your .GLB file is rendered with WebGL.
Why is my OBJ model grey or missing textures?
OBJ keeps materials in a separate .mtl file and textures as images. Select or drop all of them together with the .obj and the viewer will link them up automatically.
How accurate are the volume and weight?
For watertight meshes the volume is exact for the triangles in the file. The weight assumes PLA at 1.24 g/cm³ and 100% infill, so a sliced print with lower infill will weigh less.
My model looks lying on its side. What now?
CAD and 3D-printing files usually treat Z as "up", while games and glTF use Y. Switch Up: Y / Z in the toolbar.
Can I open STEP or IGES files here?
Those are CAD formats that store exact surfaces rather than triangles. Open them in our CAD Viewer, which converts them to a mesh.
