<div>{{APIRef("WebGL")}}</div>

<p>The <strong>WebGLFramebuffer</strong> interface is part of the <a href="/en-US/docs/Web/API/WebGL_API">WebGL API</a> and represents a collection of buffers that serve as a rendering destination.</p>

<h2 id="Description">Description</h2>

<p>The <code>WebGLFramebuffer</code> object does not define any methods or properties of its own and its content is not directly accessible. When working with <code>WebGLFramebuffer</code> objects, the following methods of the {{domxref("WebGLRenderingContext")}} are useful:</p>

<ul>
 <li>{{domxref("WebGLRenderingContext.bindFramebuffer()")}}</li>
 <li>{{domxref("WebGLRenderingContext.createFramebuffer()")}}</li>
 <li>{{domxref("WebGLRenderingContext.deleteFramebuffer()")}}</li>
 <li>{{domxref("WebGLRenderingContext.isFramebuffer()")}}</li>
</ul>
