How to convert GLB to OBJ online
Step 1: Open your GLB file
Drag the .glb file onto the drop zone. The GLB to OBJ converter parses the scene — meshes, hierarchy and transforms — and reports vertex and triangle counts for what will be exported.
Step 2: Preview the scene
Orbit the model and use wireframe to study the mesh. Because world transforms are baked before export, what you see is exactly the geometry the GLB to OBJ conversion will write — nested objects included.
Step 3: Convert and download the OBJ
Press Convert to OBJ and save the file. The output keeps your input name — character.glb becomes character.obj — ready for Blender, Maya, ZBrush or any OBJ-friendly tool.
The GLB to OBJ converter keeps the same honest workflow as every tool here: preview what you have, convert on purpose, download the result. Everything runs locally in the browser.
What does GLB to OBJ conversion preserve?
OBJ is a geometry exchange format, so the GLB to OBJ converter focuses on meshes: vertices, faces and their positions in the scene. The tool is upfront about its limits — complex GLB materials, embedded textures and animations may not be preserved, because standard OBJ export writes geometry rather than a full PBR package.
In modeling workflows this is usually the desired outcome: artists take the OBJ into a DCC tool, re-UV or remesh as needed, and rebuild materials there. The GLB to OBJ conversion hands over clean geometry with correct transforms instead of pretending to be lossless.
GLB vs OBJ: which format when?
GLB for delivery, OBJ for editing
GLB is compact, web-ready and self-contained — ideal for viewers, configurators and AR. OBJ is verbose, human-readable and universally imported, which makes it the better input for modeling, sculpting and retopology tools. Convert GLB to OBJ when an asset leaves the runtime world and enters the authoring world.
What about MTL and textures?
Classic OBJ workflows pair the mesh with an .mtl file and image textures. The current GLB to OBJ converter exports the geometry file itself; a bundled OBJ + MTL + texture archive is a planned extension. For pure geometry hand-off, the OBJ alone already opens everywhere.
Local, private GLB to OBJ conversion
Licensing terms and NDA schedules make uploads unattractive for finished assets. The GLB to OBJ converter therefore processes files entirely on your device: parsing, transform baking, OBJ writing and the download blob are all created locally in your tab.
That also means GLB to OBJ conversion starts the moment you click — no queue, no round trip, no backend size policy. Files up to 250 MB are supported; above 100 MB a soft warning notes the extra memory and parsing time. Offline, on a plane or in a secure studio network, the converter keeps working exactly the same way.
GLB to OBJ in real workflows
Artists meet the GLB to OBJ converter at a specific moment: a finished web asset needs reworking. A configurator model requires new UVs, a generated mesh needs retopology, a game prop becomes the base for a print-quality version. Converting GLB to OBJ moves the model from the delivery format into the editing format without a detour through export dialogs in desktop software.
Educators and students use the same path from the opposite direction: OBJ's readable structure makes it ideal for teaching mesh fundamentals, while GLB remains the format students actually encounter online. A quick GLB to OBJ conversion turns any web asset into study material, and because everything happens in the browser, classroom machines need no software rollout at all — every student just opens the GLB to OBJ page and works.
What to expect after converting GLB to OBJ
The OBJ file opens in every DCC tool with vertices, faces and positions intact. Expect to rebuild materials in the target application — the converter states this plainly rather than promising a lossless transfer. For geometry work like retopology, sculpting or 3D printing preparation, the GLB to OBJ output is exactly what the next tool needs, and the plain-text structure of OBJ makes the file easy to inspect, diff and script against.
Pairing with the viewers
Check the source in the GLB viewer before converting, and inspect the exported geometry in the OBJ viewer afterwards. Comparing the two previews side by side confirms that the GLB to OBJ conversion preserved everything you care about, from overall scale down to the smallest detail mesh.
GLB to OBJ FAQ
7 × Q&AIs this GLB to OBJ converter free?
Yes. GLB to OBJ conversion is free, unlimited and requires no account.
Are materials and textures exported?
The converter exports OBJ geometry; complex GLB materials, embedded textures and animations may not be preserved. The notice beside the button says exactly this.
Does the OBJ open in Blender or Maya?
Yes. The exported OBJ is standard geometry that imports into Blender, Maya, 3ds Max, ZBrush, MeshLab and virtually every DCC tool.
Are transforms handled correctly?
Yes. World transforms of nested nodes are baked into the vertices before writing, so the OBJ matches the preview exactly.
Is my GLB uploaded anywhere?
No. The GLB to OBJ converter runs entirely in your browser — nothing is transmitted or stored.
Can it also convert .gltf files?
Self-contained .gltf files work like GLB. If your .gltf references external .bin or texture files, re-export it as GLB first.
What is the file size limit?
250 MB hard limit, with a soft performance warning above 100 MB.
