Fast local mesh inspector

Free Online OBJ Viewer

Open a .obj mesh directly on this device, rotate it from every angle and check its geometry counts before editing, converting or sharing it.

Try a local OBJ sample

Choose a classic model to test the viewer before opening your own file.

What this OBJ viewer checks

OBJ is a readable mesh format used across modeling, sculpting, rendering and game pipelines. It can contain several named objects and groups, vertex positions, normals and UV coordinates, with materials usually referenced in a separate MTL file.

  1. 01 Choose or drop a .obj file.
  2. 02 Let the local parser build the mesh groups.
  3. 03 Rotate, zoom and inspect vertices, faces and objects.

OBJ compatibility

Feature Status What to expect
Vertices and polygon faces Supported Polygons are triangulated for display
Named objects and groups Supported Counted as separate scene meshes
Normals and UVs Supported Used when present in the OBJ
External MTL files Not loaded Use a packaged GLB to carry materials safely
External textures Not loaded No linked network resources are requested

Private local processing

The browser reads the selected bytes and sends them straight to the local parser and 3D renderer. There is no model upload endpoint, account, storage bucket or server-side processing step.

Limits to know

This single-file viewer does not request external MTL files or texture images, which prevents a local model from triggering outside network requests. The geometry remains inspectable with safe default materials.

Convert or inspect another format

OBJ to STL Prepare OBJ geometry for common 3D-printing workflows. OBJ to GLB Move the mesh into a compact web-native container.

Frequently asked questions

Can I view OBJ files without uploading them?

Yes. The OBJ text is parsed and rendered entirely in your browser.

Does this OBJ viewer load MTL and texture files?

No. This page accepts one OBJ file and deliberately avoids linked resource requests. It applies a neutral material so you can inspect the geometry safely.

Can the viewer open OBJ files with quads?

Yes. The OBJ loader triangulates polygon faces for WebGL display.

Which OBJ conversions are available?

You can convert OBJ to STL, GLB or glTF locally using the related TripoSR.ai converter pages.
