An STL 3D model viewer allows you to visualize STL (STereoLithography) 3D models in an interactive environment. Our online STL 3D model viewer renders your 3D models with realistic lighting, shadows, and materials, making it easy to inspect designs, verify geometry, and share 3D content. STL files are commonly used in 3D printing, CAD design, and rapid prototyping, containing triangular mesh data that defines the surface geometry of 3D objects.
Your STL 3D models never leave your device. All 3D rendering happens locally in your browser using WebGL and Three.js, ensuring your designs remain private and secure.
High-quality 3D visualization with realistic lighting, shadows, contact shadows, and environment reflections for professional model inspection.
Full 3D navigation with mouse controls, auto-rotation mode, customizable colors, and multiple environment lighting options.
View STL 3D models instantly in your web browser without downloading or installing any 3D modeling software.
Yes, our STL 3D model viewer is completely safe because your files never leave your browser. All 3D rendering happens locally on your device using WebGL technology, ensuring your models remain private and secure.
Our STL 3D model viewer supports both binary and ASCII STL file formats, which are the two standard formats used for STL files in 3D printing and CAD applications.
Yes, you can customize the model color using the color picker, toggle auto-rotation, switch between different environment lighting presets, and take screenshots from any angle.
No, there are no artificial file size limits. The STL 3D model viewer processes files entirely in your browser, so the only limitation is your device's available memory and processing power.
Left-click and drag to rotate the model, scroll wheel to zoom in/out, and right-click and drag to pan the view. These standard 3D navigation controls make it easy to examine your STL 3D model from every angle.
