View OBJ files instantly in your browser with our free online OBJ viewer. Supports materials and textures. No downloads or sign-up required.
OBJ (Wavefront Object) is a widely adopted 3D model format originally developed by Wavefront Technologies for their Advanced Visualizer software. The format has become one of the most universal interchange formats in the 3D graphics industry, supported by nearly every 3D modeling and rendering application.
OBJ files store geometry data including vertices, texture coordinates, vertex normals, and polygon faces. Unlike STL, OBJ files can reference an external MTL (Material Template Library) file that defines surface materials, colors, and textures, making them suitable for visualization workflows that require appearance data beyond raw geometry.
The OBJ format uses a simple, human-readable text structure that makes it easy to parse and debug. Each line starts with a keyword that identifies the data type: v for vertices, vt for texture coordinates, vn for normals, and f for faces. This straightforward design is a major reason for the format's longevity and universal adoption across tools like Blender, Maya, and 3ds Max.
Drag and drop your .obj file onto the viewer above, or click the upload area to browse your device. The file loads instantly in your browser.
Rotate, pan, and zoom to inspect every detail of your 3D model. Toggle wireframe view and use measurement tools to check geometry.
Take screenshots, toggle view modes, or share your model. All processing happens locally in your browser for complete privacy.
Load OBJ files with their associated MTL material definitions to see colors and surface properties in the viewer.
View texture-mapped OBJ models with UV coordinates rendered accurately in real time.
Vertex normals in OBJ files enable smooth shading for a polished, realistic appearance in the browser.
OBJ files can contain multiple named objects and groups, all rendered together in a single viewport.
