Drop a .obj below and download it as a self-contained .gltf — glTF 2.0 JSON with the geometry embedded. The conversion runs locally in your browser; if you'd rather have the compact binary form, the OBJ to GLB converter produces a .glb instead.

glTF 2.0 is the Khronos standard for 3D delivery — loadable by three.js, Babylon, <model-viewer> and every modern engine.
Unlike binary GLB, the .gltf output is plain JSON — useful when a pipeline wants to inspect or post-process the asset.
three.js parses the OBJ and writes glTF in browser memory. Nothing is uploaded anywhere.
Drag the .obj file in — the geometry renders as a live preview.
One click re-exports the mesh as glTF 2.0 JSON with embedded buffers.
Use the .gltf in web viewers, engines or toolchains that consume glTF.
Both hold identical glTF 2.0 data. Pick .gltf (this tool) when a toolchain expects JSON or you want to read and tweak the file by hand; pick .glb (the OBJ to GLB converter) for deployment, since the binary is roughly a third smaller and universally accepted. Converting between the two later is lossless.
A browser tool reads the .obj you drop, but not the .mtl and texture files it references on your disk. The glTF therefore ships with a neutral standard material — geometry, normals and UVs are fully preserved, so assigning or generating textures downstream (in Blender, or with Sculpty's AI texturing studio) works normally.
Yes — free, unlimited and signup-free, like all Sculpty mini tools.
No. The file converts in your browser's memory and downloads directly.
Geometry buffers are embedded as base64 text so the file stays self-contained. If size matters, export GLB instead — same data, binary container, smaller file.
Yes — texture coordinates present in the OBJ carry into the glTF, ready for texturing later.
Type a prompt, get a textured 3D model in about a minute — then download it as GLB, STL, OBJ, FBX or USDZ.
