Open OBJ Files Online
OBJ is a long-established text format for 3D meshes. Materials and textures live in a separate .mtl file and image files that the model refers to by name.

Frequently asked questions
Is my OBJ file uploaded?
No. The file is read by your browser and shown on your own device. Nothing is sent to a server, and it is gone when you close the tab.
How do I open an OBJ file without installing software?
Drop the .obj, .mtl file on this page. It opens straight away in the 3D Model Viewer, on Windows, macOS, Linux, Android and iPhone alike.
What if my OBJ file doesn't open?
The viewer checks the file's content, not just its name. If it is damaged or not really an OBJ file, you'll see an error or can switch to the hex view to look at the raw bytes.
