Upload Your STL 3D Model
Drag & drop your STL file or click to browse and select the 3D model file you want to view from your device.
Explore Your 3D Model
Use mouse controls to rotate (left-click + drag), zoom (scroll wheel), and pan (right-click + drag) around your 3D model.
Customize Appearance
Change the model color using the color picker, toggle auto-rotation, and switch between different environment lighting presets.
Capture & Share
Take screenshots of your model from any angle and save them as PNG images for documentation or sharing purposes.
Interactive 3D Model Visualization
View STL 3D models with full 3D interaction - rotate, zoom, and pan to examine your models from every angle
Customizable Appearance
Change model colors, adjust environment lighting, and choose from multiple lighting presets to enhance visualization
100% Browser-Based
All processing happens locally in your browser - no server uploads, ensuring complete privacy and security for your 3D models
Advanced Controls & Features
Auto-rotation mode, screenshot capture, model information display, and professional grid overlay for precise viewing
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.
Complete Privacy & Security
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.
Professional 3D Rendering
High-quality 3D visualization with realistic lighting, shadows, contact shadows, and environment reflections for professional model inspection.
Interactive Controls
Full 3D navigation with mouse controls, auto-rotation mode, customizable colors, and multiple environment lighting options.
No Software Installation
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.
