GLTF 3D Model Viewer - Free Online Tool
Instantly view your GLTF 3D models in our fast, free online tool. No software installation required. Rotate, pan, zoom, and inspect your model in the browser.
View GLTF 3D models in your browser
The Sloyd 3D viewer lets you quickly inspect a GLTF file without opening heavy desktop tools. Rotate, pan, and zoom to check proportions, shapes, and overall structure — fast previews and quick validation, not editing.
Popular file formats supported
Alongside GLTF, the viewer supports OBJ, GLB, STL, PLY — covering game development, real-time engines, and 3D printing workflows.
No login required
Upload and view your GLTF files without creating an account. Sign in only if you want to export, generate new models, or continue working inside Sloyd.
Free for 3D creators
The online GLTF viewer is free and intended for quick inspection and review. Useful when you just need to open a file, verify that it looks correct, or check a model before moving it into another tool or engine.
