OBJ Viewer

Open .obj 3D models in your browser. Drag in an OBJ file to rotate, zoom and pan, toggle wireframe, read its size and triangle count, and grab a screenshot. The model opens locally and is never uploaded.

Open an OBJ file in the browser and check its geometry without opening heavier modelling software. This free OBJ viewer reads the .obj from your device so you can rotate, zoom, pan and toggle wireframe. See the triangle count and the model's real dimensions, and grab a screenshot to use as a reference. The file is rendered locally and never uploaded, which keeps a private model private.

How to use it

  1. 1

    Open your OBJ

    Drag a .obj file onto the page or click Open model. The model opens locally and stays on your device.

  2. 2

    Orbit and zoom

    Left-drag to rotate, scroll to zoom and right-drag to pan. Toggle Wireframe to judge how dense the mesh is.

  3. 3

    Read and capture

    The info bar reports the triangle count and dimensions. Save a screenshot to keep as a reference.

When it comes in handy

Preview a classic model

OBJ is a long-standing, widely exchanged format, open one to check its geometry quickly.

Inspect before importing

Look over an OBJ shape and density before bringing it into heavier software.

Capture a reference

Frame the model and save a PNG to use as a reference image.

Opens locally & 100% in your browser

Your model is read and rendered right here on your device. The file is never uploaded to a server, there is no sign-up and no size limit beyond what your browser can handle, and any screenshot you save is generated locally too.

Frequently asked questions

What is an OBJ file?
OBJ is one of the oldest and most widely supported 3D formats. It stores a model's geometry, vertices, faces and texture coordinates, as plain text, and is exported by almost every 3D tool, which makes it a common choice for exchanging models between programs.
Will my OBJ colours and textures show?
OBJ stores materials in a separate .mtl file and textures in further image files, which a single-file drop does not include, so the model is shown in a neutral shaded material here. The geometry, scale and triangle count are all accurate; this viewer focuses on inspecting the mesh itself.
Is my OBJ uploaded, or does it stay local?
It stays local. The .obj is read and drawn on your own device and never sent to a server, so nothing you open leaves your machine. There is no account and no upload step.
