STL Viewer
View 3D printing STL files with rotate, zoom, and wireframe controls. Supports both ASCII and binary STL formats.
Open STL Viewer →OBJ Viewer
View Wavefront OBJ 3D model files with material (MTL) support. Widely used in CAD and 3D modeling software.
Open OBJ Viewer →GLTF/GLB Viewer
View GLTF and GLB 3D models with PBR materials, skeletal animations, and morph targets. The modern standard for web 3D.
Open GLTF Viewer →PLY Viewer
View PLY point clouds and meshes from 3D scanning and LiDAR. Supports vertex colors and automatic point cloud detection.
Open PLY Viewer →View 3D Models Without Installing Software
DataViewer's 3D viewers use WebGL and Three.js to render your 3D files directly in the browser. There's nothing to download or install — just drag and drop your file and start exploring.
Our 3D viewers are perfect for:
- 3D printing — Preview STL files before sending to your printer
- Game development — Quickly inspect GLTF/GLB assets with animations
- CAD & engineering — Review OBJ models with material data
- 3D scanning & LiDAR — Visualize PLY point clouds and meshes
- Architecture — Share and review 3D models without specialized software

2
Drop Your File
Drag and drop your 3D file or click to browse. The model renders instantly using your browser's GPU.
3
Explore in 3D
Rotate, zoom, and pan your model. Toggle wireframe mode and view geometry statistics.
3D Viewer FAQ
What 3D file formats are supported?
We support four popular 3D formats: STL (Stereolithography, used in 3D printing), OBJ (Wavefront with MTL material support), GLTF/GLB (the modern web 3D standard with PBR materials and animations), and PLY (point cloud and mesh data from 3D scanning and LiDAR).
Are my 3D files uploaded to a server?
No. All 3D rendering happens 100% in your browser using WebGL. Your files are never uploaded to any server — they stay on your device at all times.
What's the maximum file size?
Our 3D viewers support files up to 100MB. This covers the vast majority of 3D printing models, game assets, and scanned data.
Do I need WebGL?
Yes, WebGL is required for 3D rendering. All modern browsers (Chrome, Firefox, Safari, Edge) have WebGL enabled by default.
Which format should I use?
Use STL for 3D printing files, OBJ for CAD models with materials, GLTF/GLB for web-optimized models with animations and PBR materials, and PLY for point cloud or 3D scan data.
Can I view animated 3D models?
Yes! The GLTF/GLB viewer supports skeletal animations and morph targets. Other formats (STL, OBJ, PLY) are static geometry only.
