Convert GLTF to OBJ Online — Free
Upload a GL Transmission Format file and download it as Wavefront OBJ. Runs entirely in your browser — no server uploads.
About These Formats
GL Transmission Format
GLTF is the Khronos open standard for 3D assets — a JSON-based format that describes scenes, meshes, materials, animations, and cameras with external texture files.
Used with
WebGL applications, game engines, AR/VR platforms, and cross-tool 3D workflows.
Wavefront OBJ
OBJ is a simple, human-readable text format that stores 3D geometry (vertices, faces, texture coordinates, and normals). It is one of the most universally supported formats.
Used with
Blender, Maya, Cinema 4D, 3ds Max, ZBrush, and virtually any 3D application.
What Transfers from GLTF to OBJ
A breakdown of which data survives the GLTF-to-OBJ conversion.
3D Geometry
Vertices, faces, and normals always transfer
Textures & Materials
Diffuse/albedo map only — PBR maps (roughness, metallic, normal) not supported
Animations
Animations dropped — OBJ is a static format
Vertex Colors
OBJ does not support vertex colors
Multiple Objects
Scene hierarchy and multiple objects transfer
When to Convert GLTF to OBJ
Convert GLTF to OBJ for maximum compatibility with 3D software. OBJ is supported by virtually every 3D application including Blender, Maya, Cinema 4D, and ZBrush. It is a simple text format that stores geometry and basic material references.
GLTF to OBJ — What to Know Before Converting
GLTF files can contain skeletal animations and morph targets. OBJ is a static format — animations will not carry over, and the converter exports the mesh in its rest pose. To preserve animation data, convert to GLB or FBX instead.
GLTF stores a full PBR texture set — albedo, roughness, metallic, normal, and occlusion maps. OBJ's material model only supports diffuse colour and basic specular; roughness, metallic, and normal maps cannot be represented. Export those PBR maps separately from your source tool before converting if you need them downstream.

Tips for the Best GLTF to OBJ Result
Keep the OBJ, MTL, and all texture images in the same folder. MTL paths are relative — separating the files breaks material references.
Unity uses a left-hand coordinate system; OBJ uses right-hand. If imported geometry looks mirrored, flip the Z-axis in Unity's import settings.
For files over 50 MB, run the Mesh Optimizer first to reduce polygon count and improve compatibility with older software.
When sharing an OBJ, zip the OBJ, MTL, and all texture images together so the recipient's software can resolve the material paths.
Common Reasons to Convert GLTF to OBJ
- →DCC editing: importing into Blender, Maya, Cinema 4D, ZBrush, or any major 3D application for editing or rendering
- →Maximum compatibility: OBJ is universally supported — use it when you don't know which software the recipient will use
- →CAD and simulation: many engineering and CAD packages accept OBJ for geometry import and measurement
- →Client delivery: a transparent, widely-readable format when sharing with collaborators who need broad tool support
Frequently Asked Questions
How do I convert GLTF to OBJ?
Upload your .gltf file using the tool above, confirm the source format is set to GLTF and the target is OBJ, then click Convert. The file processes in your browser and you can download it immediately.
Does converting GLTF to OBJ preserve textures?
OBJ stores geometry only. Textures and materials will not be included in the output.
Is this converter free?
Yes, completely free. No account, no usage limits, no hidden fees.
Are my files uploaded to a server?
No. All processing happens locally in your browser using WebGL. Your files never leave your device.
