### Remarks

Uncompressed AssetBundles are large, but are the fastest to access once downloaded. Uncompressed bundles are 16-byte aligned.

This BuildCompression is only supported for recompressing AssetBundles at runtime with [AssetBundle.RecompressAssetBundleAsync](/engine/6000.7/script-reference/unityengine/assetbundle/recompressassetbundleasync.md). It is not available for building AssetBundles or content directories. Use Uncompressed for building AssetBundles and for content directory builds with [BuildPipeline.BuildContentDirectory](/engine/6000.7/script-reference/unityeditor/buildpipeline/buildcontentdirectory.md).
