Convert glTF to OBJ - Free Online Converter
Drop a .gltf file below and download it as .obj in seconds. The conversion runs entirely in your browser - no upload, no signup, no watermark. Self-contained .gltf files convert directly; files with external .bin buffers should be exported as .glb first.

Done in seconds
Your glTF converts to OBJ locally in your browser - no upload queue, no waiting.
Private by design
Your file never leaves your device. Nothing is uploaded, nothing is stored.
Free, no strings
No signup, no watermark, no file limit - convert as many files as you need.
How to convert gltf to obj
Drop your GLTF file
Drag the .gltf file into the converter above or click to browse. No account and no upload - the file stays on your device.
Conversion runs in your browser
The model is parsed and rewritten locally, in seconds for typical files. Geometry is carried over 1:1 - no remeshing, no quality loss.
Download the OBJ
The .obj download starts from the same spot. Convert as many files as you like - there is no limit or watermark.
glTF and OBJ, explained
What is glTF?
glTF is the JSON flavor of the same Khronos standard behind GLB. The scene description is human-readable JSON, typically pointing at external binary buffers and texture images. Same capabilities as GLB - PBR materials, animations, real units - in a multi-file layout.
The multi-file layout makes .gltf convenient to inspect and edit but fragile to share: if the .bin or textures go missing, the file breaks. For distribution, most pipelines pack glTF into single-file GLB - the conversion this fleet does in one click.

What is OBJ?
OBJ is the plain-text workhorse of 3D interchange. It stores vertices, faces, UV coordinates, and normals in a human-readable file, with materials referenced from a companion .mtl file. Practically every 3D application of the last 30 years can read it.
Because OBJ splits materials and textures into separate files, a bare .obj carries geometry and UVs but shows up untextured unless the .mtl and texture images travel with it. It has no units, no rigging, and no animation - which keeps it simple and universally compatible.
- Developed by
- Wavefront Technologies (circa 1990)
- Structure
- Plain-text geometry, with materials in a separate .mtl file
- Used by
- Blender, Maya, 3ds Max, ZBrush, game engines, 3D scanners
What survives the gltf to obj conversion
Format conversion is honest work: some data has nowhere to go in the target format. Here is exactly what carries over.
Mesh geometry
Every mesh in the scene is carried over exactly, with node transforms baked into the vertices.
UV coordinates & normals
Texture coordinates and normals are written into the OBJ for clean downstream texturing and shading.
Scene assembly
The node hierarchy is flattened with transforms applied - the OBJ matches the assembled scene layout.
PBR materials & textures
The output is the .obj alone - no .mtl or textures. OBJ's 1990s material model cannot represent glTF PBR anyway.
Animations
OBJ is static; animation clips are dropped and the mesh exports in rest pose.
When should you convert glTF to OBJ?
Convert to OBJ when a glTF asset needs to enter an older pipeline: sculpting tools, CAD, renderers, or scripts that predate glTF. OBJ remains the most universally accepted mesh format ever shipped.
Keep glTF for the modern stack - web viewers, engines, and AR pipelines read it natively with materials and animation intact. Convert only for tools that genuinely cannot.
And if what you actually need is a new model rather than a new file format: 3D AI Studio's main tool can generate 3D models from photos with AI - with exports to every format on this page.
