About this tool: Free OBJ Viewer
Preview OBJ mesh files locally in the browser before cleanup, import, conversion, or delivery. No upload required — everything runs locally in your browser for privacy and speed.
Common use cases
- OBJ is useful for geometry exchange, but texture and material references may travel separately.
- Use OBJ preview before conversion when you only need to verify mesh shape.
Opening an OBJ, and finding out what is missing
OBJ is a mesh plus a sibling .mtl plus the texture images. A viewer is how you find out which of those you actually received, before you spend an afternoon rebuilding a material that simply did not ship.
A quick OBJ check
- 1
Confirm the mesh loads at all
If nothing opens, the file is malformed or truncated rather than merely missing a material.
- 2
Look at the material, not just the shape
Grey means the .mtl is missing; black usually means the .mtl is present but its texture paths are broken.
- 3
Ship the set, not the single file
Zip the .obj, the .mtl and every texture it references, keeping the folder structure the .mtl expects.
OBJ viewer questions
- Why is my OBJ grey or black?
- Grey: no .mtl travelled with it. Black: the .mtl is there but its texture paths are absolute paths from another machine.
- OBJ or GLB for a website?
- GLB. It is one file with textures embedded, and browsers load it natively.
- Can I open an OBJ without uploading it?
- Yes. The file is parsed in your browser, so the mesh never leaves your machine.
Quick tips
- OBJ is useful for geometry exchange, but texture and material references may travel separately.
- Use OBJ preview before conversion when you only need to verify mesh shape.
