# LZMA

> LZMA Compression.

## Definition

* **Type:** Field
* **Namespace:** [UnityEngine](/engine/6000.7/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
public static readonly BuildCompression LZMA
```

### Remarks

LZMA compression gives the smallest possible download size, but has relatively slow decompression resulting in higher apparent load times and greater memory use at runtime.

This BuildCompression is supported for building AssetBundles and content directories with [BuildPipeline.BuildContentDirectory](/engine/6000.7/script-reference/unityeditor/buildpipeline/buildcontentdirectory.md). It is not available for recompression at runtime.
