<p>The <strong><code>URL</code></strong><strong> </strong>interface represent an object providing static methods used for creating object URLs.</p>

<p>When using a user agent where no constructor has been implemented yet, it is possible to access such an object using the non-standard {{domxref("Window.URL")}} properties (prefixed with Webkit- and Blink-based browser as <code>Window.webkitURL</code>).</p>

<dl>
 <dt>{{domxref("URLUtils.href")}}</dt>

 <dt>{{domxref("URLUtils.protocol")}}</dt>
 <dd>Is a {{domxref("DOMString")}} containing the protocol scheme of the URL, including the final <code>':'</code>.</dd>
 <dt>{{domxref("URLUtils.host")}}</dt>
 <dd>Is a {{domxref("DOMString")}} containing the host, that is the <em>hostname</em>, a <code>':'</code>, and the <em>port</em> of the URL.</dd>
 <dt>{{domxref("URLUtils.hostname")}}</dt>
 <dd>Is a {{domxref("DOMString")}} containing the domain of the URL.</dd>

 <dd>Is a {{domxref("DOMString")}} containing the port number of the URL.</dd>
 <dt>{{domxref("URLUtils.pathname")}}</dt>
 <dd>Is a {{domxref("DOMString")}} containing an initial <code>'/'</code> followed by the path of the URL.</dd>
 <dt>{{domxref("URLUtils.search")}}</dt>

 <dt>{{domxref("URLUtils.origin")}} {{readonlyInline}}</dt>
 <dd>Returns a {{domxref("DOMString")}} containing the origin of the URL, that is its scheme, its domain and its port.</dd>
</dl>

<dl>
 <dt>{{domxref("URLUtils.searchParams")}}</dt>
 <dd>Returns a {{domxref("URLSearchParams")}} object allowing to access the GET query arguments contained in the URL.</dd>
</dl>

<h2 id="Constructor">Constructor</h2>

<dl>
 <dt>{{domxref("URL.URL", "URL()")}}</dt>
 <dd>Creates and return a <code>URL</code> object composed from the given parameters.</dd>

<h2 id="Methods">Methods</h2>

<p><em>The <code>URL</code> interface implements methods defined in {{domxref("URLUtils")}}.</em></p>

<dl>
 <dt>{{domxref("URLUtils.toString()")}}</dt>
 <dd>Returns a {{domxref("DOMString")}} containing the whole URL. It is a synonym for {{domxref("URLUtils.href")}}, though it can't be used to modify the value.</dd>
</dl>

<h2 id="Static_methods">Static methods</h2>

<dl>
 <dt>{{ domxref("URL.createObjectURL()") }}</dt>
 <dd>Returns a {{domxref("DOMString")}} containing a unique blob URL, that is a URL with <code>blob:</code> as its scheme, followed by an opaque string uniquely identifying the object in the browser.</dd>
 <dt>{{ domxref("URL.revokeObjectURL()") }}</dt>
 <dd>Revokes an object URL previously created using {{ domxref("URL.createObjectURL()") }}.</dd>

<h2 id="Browser_compatibility">Compatibilidade com navegadores</h2>

<p>{{Compat("api.URL")}}</p>

<p>[1] From Gecko 2 (Firefox 4) to Gecko 18 included, Gecko supported this interface with the non-standard <code>nsIDOMMozURLProperty</code> internal type. As the only to access such an object was through {{domxref("window.URL")}}, in practice, this didn't make any difference.</p>

<h2 id="Chrome_Code_-_Scope_Availability">Chrome Code - Scope Availability</h2>

<p>To use from chrome code, JSM and Bootstrap scope, you have to import it like this:</p>

<pre class="brush: js notranslate">Cu.importGlobalProperties(['URL']);
</pre>

<p><code>URL</code> is available in Worker scopes.</p>
