# Create Draco Files

For creating Draco™ (`.drc`) files, there are multiple options.

## Command Line Tool

Draco's [Encoding Tool][dracoEncoder] is a command line tool that is able to convert a mesh or point cloud into a Draco (`.drc`) file. It supports the following input types:

- [Wavefront OBJ (`.obj`)][obj]
- [PLY][ply]
- [STL][stl]

Example for encoding a Wavefront OBJ (`input.obj`) into a Draco file (`output.drc`):

```shell
draco_encoder -i input.obj -o output.drc
```

See the [`draco_encoder`][dracoEncoder] documentation for usage details.

Unfortunately there's no binary distribution, so you have to build the executable yourself following Draco's [build instructions][dracoBuild].

> **Tip:** Similar to the Encoding Tool there's a [glTF Transcoding Tool][dracoGltfTranscoder] that it able to apply Draco compression on glTF files. See [Draco and glTF](do-more.md#draco-and-gltf) for more information.

## Within Unity

In the [*Scene/GameObject Encoding/Decoding via Menu* sample](sample-scene-encode-decode.md) you'll find an Editor script that lets you encode meshes to Draco within the Editor.
