Drop a .obj below and download a single self-contained .glb ready for web viewers, Unity, Unreal and AR. The conversion runs locally in your browser — private and instant.
Converted locally · never uploaded · no signup
OBJ ships as .obj + .mtl + textures. GLB packs a model into a single binary that web and engine pipelines load natively.
three.js parses the OBJ and exports binary glTF locally. Nothing is uploaded anywhere.
The output loads in three.js, Babylon, <model-viewer>, Unity, Unreal, Blender and AR runtimes.
Drag the .obj file in — the geometry renders as a live preview.
Click once; the mesh is re-exported as binary glTF 2.0.
Use the .glb in your site, engine or AR experience immediately.
OBJ is great for DCC interchange but clumsy for delivery: it is text-based, splits materials into a sidecar .mtl and leaves textures as loose files. GLB is the delivery format of modern 3D — binary, compact, self-contained and loadable by every web viewer and game engine without conversion plugins.
This tool converts the .obj geometry file. Since browsers can't fetch your local .mtl and texture files alongside it, the GLB is exported with a neutral standard material — the geometry, normals and UVs (when present in the OBJ) are preserved, so re-texturing downstream is straightforward.
Yes. Free and unlimited, no account required.
No — the file is converted in your browser's memory and downloaded directly. It never reaches a server.
Yes, texture coordinates present in the OBJ are carried into the GLB, so you can apply textures to the converted model later.
OBJ references textures via a separate .mtl file and image files that a browser tool can't read from disk alongside your .obj. Convert the geometry here, then assign or generate textures in Blender or Sculpty's texturing studio.
Type a prompt, get a textured 3D model in about a minute — then download it as GLB, STL, OBJ, FBX or USDZ.
