# Basis Universal GPU Texture Compression
Basis Universal is a "[supercompressed](http://gamma.cs.unc.edu/GST/gst.pdf)"
GPU texture and texture video compression system that outputs a highly
compressed intermediate file format (.basis) that can be quickly transcoded to
a wide variety of GPU texture compression formats.
[GitHub](https://github.com/BinomialLLC/basis_universal)
## Transcoders
Basis Universal texture data may be used in two different file formats:
`.basis` and `.ktx2`, where `ktx2` is a standardized wrapper around basis texture data.
For further documentation about the Basis compressor and transcoder, refer to
the [Basis GitHub repository](https://github.com/BinomialLLC/basis_universal).
The folder contains two files required for transcoding `.basis` or `.ktx2` textures:
* `basis_transcoder.js` — JavaScript wrapper for the WebAssembly transcoder.
* `basis_transcoder.wasm` — WebAssembly transcoder.
Both are dependencies of `KTX2Loader`:
```js
const ktx2Loader = new KTX2Loader();
ktx2Loader.detectSupport( renderer );
ktx2Loader.load( 'diffuse.ktx2', function ( texture ) {
const material = new THREE.MeshStandardMaterial( { map: texture } );
}, function () {
console.log( 'onProgress' );
}, function ( e ) {
console.error( e );
} );
```
