Convert GLB to OBJ
Drop a .glb file and download a clean Wavefront OBJ in seconds. Reads binary glTF geometry and writes portable OBJ. Runs entirely in your browser — no upload, no signup, no watermark.
How to convert GLB to OBJ
- Drag your
.glbfile into the box above (or click to browse). - Preview the model in the viewer — drag to rotate, scroll to zoom.
- Click Convert & Download .obj. The
.objfile lands in your downloads folder.
Conversion runs in your browser via three.js. Your file never leaves your device — there's no upload, no server, and nothing is stored.
Converting a GLB file to OBJ
GLB is binary glTF — the compact, modern format for web, AR and game engines, carrying PBR materials, embedded textures, animation and a full scene graph in one file. OBJ (Wavefront) is a plain, static mesh that nearly every 3D tool can open. Converting GLB to OBJ trades GLB's rich scene data for that universal compatibility.
This converter reads the geometry from your GLB with three.js and writes a standard OBJ — vertices, normals and UV coordinates included. Because OBJ can't hold them, materials, textures and animation are not carried over. The geometry is preserved exactly, so the shape that comes out matches the shape that went in.
OBJ is the right target when a tool won't take GLB directly, or when you only need the raw mesh for editing, CAD, or 3D printing. If you need to keep materials and textures, stay in GLB; if you want a printable mesh, convert straight to STL.
Frequently asked questions
How do I convert a GLB file to OBJ?+
Drop your .glb file into the box above, preview it in the 3D viewer, then click Convert & Download .obj. Everything runs in your browser — the file is never uploaded.
Is this GLB to OBJ converter free?+
Yes. No signup, no watermark, and no file-size paywall. Flip3D reads and converts your GLB locally on your own device.
Does it keep materials, textures and colors?+
No. GLB stores rich PBR materials and embedded textures; OBJ stores geometry only. The OBJ we write has no .mtl file and no textures, so materials and color are dropped. Vertex positions, normals, and UV coordinates are preserved, so textures can be re-applied in your target app. To keep materials, stay in GLB.
Can I convert glTF (.gltf) to OBJ?+
This tool reads binary glTF — the single-file .glb. If you have a text .gltf with separate .bin and texture files, pack it into a .glb first (most exporters, including Blender, can do this), then convert. The geometry conversion is identical either way.
What happens to animations?+
They're dropped. OBJ is a static, single-frame mesh with no animation track, so any GLB animations are not carried over. Convert only when you need the geometry; keep the GLB if you need the animation.
Can I convert OBJ back to GLB?+
Yes — use the OBJ to GLB converter for the reverse direction, which lets you keep or rebuild materials. For how the formats differ, see the STL vs OBJ vs 3MF reference.
Will the OBJ open in Blender, Cinema 4D or Unity?+
Yes. OBJ is read by every major 3D app, game engine, and slicer. Converting GLB to OBJ is usually about getting the mesh into a tool that doesn't take GLB directly.
