GLB · glTF(+.bin) · OBJ · STL · PLY · FBX — parsed locally
100%
Drop a GLB or glTF and orbit it with studio lighting. Animations play back in the tab; OBJ, STL, PLY and FBX also open. Files never leave your device.
01 — Local
Parsing and rendering happen entirely in this tab. Your file is never uploaded to a server.
02 — PBR
Studio lighting with real environment reflections, orbit, zoom and frame-to-fit. Animation clips play back when present.
03 — Stats
The stats bar reports mesh count, triangle totals, materials and clips — verify a model before shipping it to the web or AR.
Questions people ask
- Can GLB files carry color and animation?
- Yes — GLB is the binary form of glTF, so one file holds geometry, PBR materials, textures and animation clips. This viewer plays the clips back and shows mesh, triangle and material counts under the viewport.
- How do I make a GLB file smaller?
- Re-encode it with the free GLB compressor: Draco or Meshopt geometry codecs plus optional mesh decimation and WebP textures, all on-device. Geometry typically shrinks 2–10× before textures are even touched.
- Where does GLB run out of the box?
- Most places: web viewers (three.js, Babylon.js), AR quick-look on iOS and Android, and current real-time engines. If a pipeline only accepts triangles — 3D printing, CNC — convert GLB to STL first.
