An OFF (Object File Format) viewer is a tool that renders and displays 3D models stored in the OFF format. OFF is a simple ASCII format that describes 3D objects using vertices and faces. Our viewer parses the OFF file structure, creates 3D geometry, and renders it with modern WebGL technology for smooth, interactive viewing.
No Software Installation
View OFF files instantly in your browser without downloading or installing any software.
Advanced 3D Features
Enjoy professional-grade 3D rendering with shadows, lighting, and multiple environment presets.
Privacy & Security
All file processing happens locally in your browser - your 3D models never leave your device.
Cross-Platform Compatible
Works on any device with a modern web browser, including Windows, Mac, Linux, and mobile devices.
OFF (Object File Format) is a simple ASCII format for representing 3D objects. It stores vertex coordinates and face connectivity information to define 3D meshes.
The viewer can handle most OFF files, but very large models (over 50MB) may take longer to load and could impact performance depending on your device.
Yes! The viewer supports OFF files with color information and will display vertex colors when available in the file.
Use your mouse to rotate (left-click + drag), zoom (scroll wheel), and pan (right-click + drag). Touch gestures work on mobile devices.
