Convert GLB to OBJ with Textures and an MTL File
Your GLB comes back as a ZIP holding the .obj, its .mtl and the texture images, ready for software without a glTF importer. OBJ stores a single static pose, so skeletons, animation and morph targets stay behind.

Why convert GLB to OBJ?
A GLB keeps geometry, materials and images together in one binary container. OBJ works the other way round: a plain-text mesh file, a companion .mtl material file, and texture images referenced by file name. That older layout is what many render plugins, retopology and sculpting tools, photogrammetry utilities and older CAD viewers still read, which is why a GLB from a web gallery or AR project often has to be turned into OBJ before it is usable.
Blender 5.1 does the work on our servers. After it imports the GLB, every image used by a material is written out next to the OBJ as its original bytes, so a PNG stays a PNG and a JPEG stays a JPEG, with the output name as a prefix. The .mtl refers to those images by bare file name, and the .obj, .mtl and images are zipped into one download named after your file, ending in .obj.zip.
What you keep: each mesh as a named object, with its UV coordinates and normals. The base color texture is linked as map_Kd and the normal map as map_Bump, and a tinted base color is kept as Kd. Coordinates keep the GLB's meter values and stay Y-up.
What you lose: OBJ has no field for glTF's packed metallic-roughness texture, so that image is included in the ZIP but not referenced in the .mtl. Vertex colors are not written. The skeleton, animation clips and morph targets are dropped, and the mesh is saved in the pose it has when exported. Draco or meshopt compression is undone, so the OBJ is usually much larger than the GLB.
How to convert GLB to OBJ with textures
- Check that you have a binary .glb. If your model is a .gltf with a separate .bin and texture folder, put them in one ZIP and use our ZIP to OBJ page instead.
- Upload the GLB. You can add up to 10 files at once without a paid plan.
- Blender imports the model, writes each material image beside the OBJ and exports the OBJ and MTL. Small models finish in a few seconds; large textured ones take longer.
- Download the .obj.zip and extract the whole folder. Keep the .obj, .mtl and images together, because the MTL refers to the images by file name only.
- Import the .obj file, not the .mtl, into your application. If the textures do not appear, point the importer at the extracted folder.
What you get from GLB to OBJ
- Texture images written from the GLB byte for byte, with no re-compression
- MTL references use plain file names, so the extracted folder can be moved anywhere
- Separate meshes kept as named objects in the OBJ
- UV coordinates and normals written for every mesh
- Base color tints written as Kd next to map_Kd so the color still matches
- Draco, meshopt and WebP-textured GLBs accepted (WebP is converted to PNG)

GLB to OBJ: questions and fixes
How do I convert GLB to OBJ with texture?
Upload the GLB above and download the ZIP. It contains the .obj, an .mtl with map_Kd pointing at the base color image and map_Bump pointing at the normal map, and the image files themselves. Extract everything into one folder and open the .obj; most applications load the .mtl and textures automatically.
Why is the download a ZIP and not an .obj file?
An OBJ cannot hold materials or images. The .mtl and the textures are separate files, and the OBJ only works when they sit next to it, so we bundle them into one archive named like model.obj.zip.
Are animations and rigs kept?
No. OBJ stores static geometry only. The skeleton, skin weights, morph targets and animation clips are dropped, and you get the mesh in a single pose. If you need the rig, convert the GLB to FBX instead.
What happens to PBR materials such as metallic and roughness?
The MTL written here links the base color and normal maps only. glTF packs metalness and roughness into one image, which MTL has no standard slot for. We still include that image in the ZIP, so you can connect it by hand in an application that understands PBR.
Why did I get "Extension KHR_gaussian_splatting is not available"?
That GLB stores a Gaussian splat capture, not a polygon mesh, and Blender's glTF importer cannot read it. OBJ could not store splats either. The same message appears for GLBs that require KTX2 compressed textures; for those, re-export the model with PNG or JPEG textures and try again.
Will the OBJ have the same size and orientation as the GLB?
Yes. Coordinates are written at the GLB's scale, which glTF defines in meters, and the OBJ stays Y-up like the source. An application that assumes millimeters will show the model 1,000 times smaller, so scale it on import if that happens.
How large can the GLB be?
Guests can upload 50 MB per file and free accounts 100 MB; the Plus plan allows 200 MB and Pro 1 GB. Every file gets up to 10 minutes of processing.
Is my model kept on your server?
Only briefly. The GLB is converted on our servers and your upload is removed right after processing. After 4 hours the download link expires and a scheduled sweep deletes the ZIP.
