<p><strong>WebGL</strong>(Web Graphics Library)은 플러그인을 사용하지 않고 웹 브라우저에서 상호작용 가능한 3D와 2D 그래픽을 표현하기 위한 JavaScript API입니다. WebGL은 HTML5 {{HTMLElement("canvas")}} 요소에서 사용할 수 있는, OpenGL ES 2.0을 대부분 충족하는 API를 제공합니다.</p>

<p>WebGL은 <a href="https://www.mozilla.org/ko/firefox/new/">Firefox</a> 4+, <a href="http://www.google.com/chrome/">Google Chrome</a> 9+, <a href="http://www.opera.com/">Opera</a> 12+, <a href="http://www.apple.com/fr/safari/">Safari</a> 5.1+, <a href="http://windows.microsoft.com/en-us/internet-explorer/download-ie">Internet Explorer</a> 11+, <a href="https://www.microsoft.com/en-us/windows/microsoft-edge">Microsoft Edge</a> build 10240+에서 사용할 수 있습니다. 그러나 사용자 장치의 하드웨어도 WebGL 기능을 지원해야 합니다.</p>

<p>{{HTMLElement("canvas")}} 요소는 <a href="/ko/docs/Web/API/Canvas_API">캔버스 API</a>를 사용해 웹 페이지에서 2D 그래픽을 그릴 때도 사용됩니다.</p>
