Free Online OBJ File Viewer
Drop an OBJ file and inspect 3D geometry in your browser. Orbit, zoom, measure, and export — no software, no plugins, no friction.
What is a OBJ file?
OBJ (Wavefront) is one of the oldest and most universally supported 3D file formats. Created by Wavefront Technologies in the 1980s, it stores mesh geometry as vertex positions, texture coordinates, normals, and face definitions. OBJ is used extensively in game development, visual effects, 3D scanning, scientific visualization, and architectural modeling.
What you can do with OBJ files in CADDaddy
CADDaddy loads OBJ files using Three.js for hardware-accelerated rendering. Get smooth 60fps navigation on complex meshes. Toggle wireframe mode to inspect topology, use section planes to view cross-sections, and share review links with teammates.
Universal format support
Open OBJ files from Blender, Maya, 3ds Max, ZBrush, and virtually any 3D application.
Wireframe inspection
Toggle wireframe mode to see triangle topology, edge flow, and mesh density.
Measurement tools
Point-to-point distance measurement with vertex snapping for dimension verification.
Export to STL or GLB
Convert OBJ to STL for 3D printing or GLB for web and AR applications.
Section plane
Slice through mesh geometry along any axis to inspect cross-sections and internal structure.
Shareable review links
Generate a review link for teammates or clients — they view the model with zero setup.
OBJ Viewer FAQ
What is an OBJ file?+
OBJ (Wavefront) is one of the most widely supported 3D geometry formats. Developed by Wavefront Technologies, OBJ files store vertex positions, normals, texture coordinates, and face definitions. The format is used across 3D modeling, game development, scientific visualization, and architectural rendering.
How do I view an OBJ file online?+
Drag and drop your .obj file into CADDaddy's viewer. It opens in your browser with full 3D orbit, zoom, and pan — no software to install, no account needed.
What is the difference between OBJ and STL?+
Both store triangle mesh geometry, but OBJ also supports texture coordinates (UVs), vertex normals, material definitions (.mtl files), and polygon groups. STL only stores raw triangle geometry. OBJ is better for visual applications; STL is the standard for 3D printing.
Can I convert OBJ to STL or GLB?+
Yes. Upload your OBJ file to CADDaddy, inspect the mesh, then export to STL for 3D printing or GLB for web and game engine use.
Does CADDaddy support OBJ materials (.mtl)?+
CADDaddy focuses on geometry visualization. Material and texture rendering from .mtl files is partially supported — vertex colors and basic materials are displayed.
Is there a file size limit?+
Free accounts handle standard OBJ files. Upgrade to Pro ($19 one-time) for larger files, unlimited exports, and advanced inspection tools.
