# Exporting GLB With Draco Compression

> How to export GLB files with Draco mesh compression from Asset Transformer Studio

Asset Transformer Studio can export binarized [glTF files](https://www.khronos.org/gltf/) (.glb), a format that's broadly used to consume 3D models on the web.

It is also possible to export .glb files using [Draco mesh compression](https://google.github.io/draco/), a method used to compress and decompress geometric meshes, making .glb files much lighter, meaning faster upload/download time.

> **Note:**
>
> In Asset Transformer Studio, **only Compression** is supported, Decompression is not supported yet.

## How To

Go to [Preferences (F9)](../../user-interface/menu-bar/edit-menu/preferences) > `IO` > `Export` > `GLTF` and enable the `ExportGLTFDraco` parameter.

There are advanced parameters that are meant to fine-tune Draco compression behavior.

### Scripting

The `ExportGLTFDraco` parameter (and the other advanced parameters as well) can be set in a script using the following command:

```python
core.setModuleProperty("IO", "ExportGLTFDraco", "True")
```
