What is a GLB viewer?
GLB is the binary form of glTF, the open standard for 3D scenes and models on the
web. Unlike STL, a .glb file can carry materials, colors, textures and
even animations in a single file. An online GLB viewer lets you open and inspect
.glb files without installing anything — handy for checking exports
from Blender, product configurators, or AR-ready assets. This viewer runs entirely
in your browser, so your files stay private.
Features
- Full material support — PBR materials and textures render as authored.
- Instant 3D preview — orbit, zoom and pan with mouse or touch.
- Wireframe & auto-rotate toggles for inspecting mesh quality.
- Model stats — file size, triangle and vertex counts at a glance.
- Private — files are parsed locally; nothing is uploaded.
More formats, same viewer
The same viewer also opens STL files, OBJ, PLY, 3MF, FBX, STEP and IGES — drop any of them on this page. Need to convert a CAD file first? Try our free STEP to STL converter or IGES to STL converter.
FAQ
- Is this GLB viewer free?
- Yes — free forever, no account, no limits.
- Are my GLB files uploaded to a server?
- No. Files are read and rendered locally in your browser via WebGL. They never leave your device.
- Do textures and materials show up?
- Yes — embedded materials and textures in the GLB render as authored. External texture files referenced by a
.gltf(non-binary) may not resolve, since only the single file is loaded; use GLB for best results. - Does it work on mobile?
- Yes — touch controls (one finger to rotate, pinch to zoom) work on phones and tablets.
