# GLB 3D Model Viewer - Free Online Tool

Instantly view your GLB 3D models in our fast, free online tool. No software installation required. Rotate, pan, zoom, and inspect your model in the browser.

## Features

### View GLB 3D models in your browser

The Sloyd 3D viewer lets you quickly inspect a GLB 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 GLB, the viewer supports OBJ, GLTF, STL, PLY — covering game development, real-time engines, and 3D printing workflows.

### No login required

Upload and view your GLB 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 GLB 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.

## How to use the GLB 3D viewer

1. **Upload your GLB file** — Open our 3D model viewer and drag and drop your GLB file into the upload zone. We also support GLB, GLTF, OBJ, STL, and PLY (max 200MB).
2. **Inspect the model** — Use the camera controls to rotate, zoom, and pan around the model. Inspect from any angle to verify proportions and surface quality.
3. **Continue your workflow** — When you are done viewing, you can generate a new 3D asset with our Image-to-3D or Text-to-3D tools — or close the page.
