How to Use the Online 3D Viewer
Preview your models in three easy steps. Our browser-based 3D viewer requires zero installation.
Upload Your File
Drag and drop a model file into the 3D viewer upload area, or click to browse your device. The 3D viewer accepts STL, OBJ, GLB, GLTF, PLY and 3MF files up to 50 MB.
Inspect and Navigate
Once loaded in the 3D viewer, use your mouse to rotate the model, scroll to zoom, and right-click to pan. Switch between standard, print-preview and wireframe rendering modes.
Analyze or Export
The 3D viewer shows mesh statistics including vertex count, face count and bounding box dimensions. Download your model in GLB, STL or OBJ format if you need a conversion.
Why Choose Our Free 3D Viewer
Professional-grade tools for inspecting and analyzing 3D models — entirely in your browser, entirely free.
Multi-Format Support
This 3D viewer handles all major file formats including STL, OBJ, GLB, GLTF, PLY and 3MF. No matter which format your model uses, it opens seamlessly.
Real-Time Rendering
Powered by WebGL and hardware acceleration, the 3D viewer delivers smooth, real-time rendering. Even complex models with hundreds of thousands of polygons display without lag.
Multiple View Modes
Toggle between standard shading, white print-preview and wireframe rendering. Each mode in the 3D viewer helps you assess different aspects of your model's geometry and surface quality.
Mesh Statistics Panel
The 3D viewer info panel displays vertex count, triangle count, bounding box dimensions and file size — essential data for quality control in 3D printing and game development.
Privacy-First Design
All processing in the 3D viewer happens locally in your browser. Your files are never uploaded to any server, ensuring complete privacy and data security.
Cross-Platform Compatibility
Our 3D viewer works on any device with a modern browser — desktops, laptops, tablets and phones. No plugins or downloads needed on Windows, Mac, Linux, iOS or Android.
3D File Formats the 3D Viewer Supports
The most widely used model formats across design, gaming, manufacturing and 3D printing — all supported by the 3D viewer.
STL Files
The standard format for 3D printing. Our 3D viewer renders STL meshes and lets you verify geometry before sending files to your printer.
OBJ Files
A universal format supported by virtually every 3D application. Open and inspect OBJ models with full geometry display inside the 3D viewer.
GLB / GLTF Files
The modern web standard for 3D content. The 3D viewer renders GLB and GLTF models with embedded textures and materials for accurate real-time previews.
PLY Files
Commonly used in 3D scanning and academic research. The 3D viewer handles PLY point clouds and polygon meshes, including those with per-vertex color data.
3MF Files
The next-generation 3D printing format. Load 3MF packages into the 3D viewer to preview print-ready models with full color and material information.
Who Benefits from This 3D Viewer
Our online tool serves professionals and hobbyists across many industries. Here is how different users rely on the 3D viewer in their daily workflows.
3D Designers & Artists
Use the 3D viewer to quick-preview exported models before importing into your main design software. Check polygon counts, surface normals and overall geometry.
3D Printing Enthusiasts
Verify STL files in the 3D viewer before starting a print job. Wireframe and print-preview modes help you spot mesh issues early, saving time and filament.
Game & AR/VR Developers
Preview game assets and AR models in the 3D viewer to check LOD, triangle counts and visual quality. GLB and GLTF files render exactly as they appear in web engines.
Engineers & Manufacturers
Load CAD exports into the 3D viewer to inspect prototypes. Verify bounding box dimensions and surface quality before CNC machining or injection molding.
