About this 3D viewer
Analyze a compatible OBJ file before conversion, sharing, or 3D printing. The inspector counts meshes, vertices, triangles, UVs, normals, material names, and referenced MTL files locally in your browser.
What does an OBJ file contain?
An OBJ file is a text-based 3D geometry format. It can store vertices, faces, normals, UV coordinates, object groups, and references to an MTL material file.
OBJ file information before conversion
Mesh statistics reveal whether a model is suitable for a particular workflow. This inspection is informational only; it does not repair geometry or guarantee 3D-print readiness.
OBJ files from Blender, Maya, and 3ds Max
Preview compatible OBJ geometry in a current Windows, macOS, or Linux browser after export from Blender, Maya, 3ds Max, SketchUp, or similar software. For the original appearance, select the companion MTL and texture images when the tool asks for them.
How to use this OBJ viewer
- Sign in and unlock OBJ tools once.
- Upload a compatible .obj file.
- Review mesh statistics and material references, then choose OBJ Texture Viewer, OBJ to GLB, or OBJ to STL as needed.

OBJ viewer FAQ
What information can OBJ Inspector show?
For compatible OBJ files, it reports mesh counts, vertices, triangles, UVs, normals, material names, and referenced MTL files.
Does OBJ Inspector edit or repair a model?
No. It is a local file-analysis tool. Use modelling, repair, or slicing software for geometry edits and printability repair.
Why does an OBJ reference an MTL file?
OBJ commonly stores material assignments in a companion MTL file, which can in turn reference texture images.
Can I view an OBJ exported from Blender, Maya, or 3ds Max?
Yes, for compatible OBJ geometry. OBJ materials commonly depend on a separate MTL file and image textures, so include those companion files when you need to inspect the original look.
What file extension does OBJ use?
This tool accepts the compatible OBJ extension shown in the upload area. Use the dedicated format viewer when a file has a related extension or an application-specific variant.
Can I use this OBJ viewer on a phone?
The page can be opened on mobile browsers, but a desktop browser is usually more practical for large files and detailed orbit, zoom, and inspection work.
Do I need to create an account to preview a OBJ file?
Yes. Sign in first, then unlock this OBJ tool once for $1.90. VIP members can also access the viewer.
