About

WebAssetStudio is an online tool to view and extract game asset bundles. It runs entirely inside your browser using JavaScript and WebAssembly.

Currently, it supports Unity assets and asset bundles (.unity3d, .assets, and various other extensions used by games) and XNA Game Studio/FNA Framework saved assets (.xnb, .xnb.deploy).

How to use

Click the 'Open...' button at the top, or drag a file onto the sidebar. To save an asset, either click the download button on the right side of the preview pane, or to save all assets, click the 'Download ZIP' button.

To use the tree, simply expand the root node (named like 'Asset' or 'Bundle'), and browse the tree to find the asset you want to extract. Generally, useful assets can be found under 'Objects' in most trees.

You are responsible for your actions with this tool.
