About iframe Tester

Our iFrame Tester is an online tool developed for developers and publishers to help them analyze whether a specific URL can be embedded within an iframe on external websites. Our iframe testing tool provides an easy way to preview how a website appears when loaded via an iframe. It helps them to save time and effort in the debugging process.

By validating URLs and checking the necessary HTTP response headers, our iframe tester provides clear feedback on whether the URL can be loaded in an iframe or not.

What is an iFrame?

An iframe (short form for inline frame) is an HTML element that allows any webpage to embed another webpage. It creates a separate window within the current webpage and external content from a URL will be displayed.

This enables developers to integrate external website content seamlessly into their own websites, such as displaying a map, video, article, media, or social media feed from another website.

What determines if a webpage can be embedded in an iframe?

The ability to embed a webpage in an iframe depends on the HTTP response headers sent by the server hosting that webpage. The presence and configuration of the X-Frame-Options header decide if the webpage can be loaded within an iframe.

Different directives or values of the X-Frame-Options header is deny, sameorigin, or allow-from and they impose different restrictions on whether the webpage can be embedded in an iframe or not.

What are HTTP response headers?

HTTP response headers are part of the server’s response when a client (such as a web browser) sends a request. These headers provide additional information and instructions to the client about how to handle the requested content. Response headers include information about caching, content type, security measures, and more.

What are X-Frame-Options header?

X-Frame-Options is one of the many HTTP response headers that control if and how a webpage can be loaded within an iframe on external websites. This header is helpful to clickjacking attacks by restricting the embedding of a webpage in iframes.

What are the different directives of X-Frame-Options and what do they mean?

The X-Frame-Options response header has three directives: ‘deny‘, ‘sameorigin‘, and ‘allow-from‘. Each directive comes with different restrictions on iframe embedding:

  1. deny‘: When the server set ‘X-Frame-Options’ to ‘deny’, it prevents the URL from being displayed within an iframe on any website, even if it’s requested from the same domain. Example: X-Frame-Options: DENY
  2. sameorigin‘: When ‘X-Frame-Options’ is set to ‘sameorigin’, it restricts the rendering of the URL in an iframe to only the same origin or domain. It prevents the URL from being displayed in an iframe on any other website. Example: X-Frame-Options: SAMEORIGIN
  3. allow-from‘: When ‘X-Frame-Options’ is set to ‘allow-from’, it permits the URL to be displayed in an iframe only if the URI specified in the directive matches the website’s origin. Example: X-Frame-Options: ALLOW-FROM https://example.com

Note: The ‘allow-from‘ directive requires specifying the exact origin (protocol, domain, and port) from which the URL can be embedded in an iframe. This directive is not supported in many modern browsers and developers should stop using it.

What is the Browser support for X-Frame-Options header

Not all browsers support all directives of the X-Frame-Options header. Most modern browsers currently support only ‘DENY’ and ‘SAMEORIGN’ directives only. However only limited browsers support ‘ALLOW-FROM’ directive. If you are a developer, consider checking the below table before you use ‘ALLOW-FROM’ directive on your website.

Web Browser DENY / SAMEORIGIN ALLOW-FROM
Google Chrome 110+ Not Supported
Safari 4.0+ Not Supported
Microsoft Edge 12+ 12 – 18
Mozilla Firefox 109+ 18 – 69
Opera 94+ Not Supported
Internet Explorer 8.0+ 9.0+

How to iframe a URL in a website?

To add an iframe to a website, you need to include an iframe element in the HTML code of your webpage. The iframe element should have its “src” attribute set to a valid URL you wish to embed. Here is the boilerplate code to add an iframe to your website:

<!DOCTYPE html>
  <html lang="en">
    <head>
      <meta charset="UTF-8">
      <meta name="viewport" content="width=device-width, initial-scale=1.0">
      <meta http-equiv="X-UA-Compatible" content="ie=edge">
      <title>Iframe Tester</title>
    </head>
    <body>
      <iframe src="https://www.geekdashboard.com"></iframe>
    </body>
</html>

This will load the content of the specified URL (https://www.geekdashboard.com) within the iframe on your webpage (depending on its X-Frame-Options header response)

How can I test if a URL can be loaded within an iframe with this tool?

To test if a URL can be displayed in an iframe using our iframe testing tool, you need to simply type or enter the URL in the input field at the top of the page. Our tool will first validate the URL and, if the URL is valid, it automatically enables the “Go” button. Now click on the “Go” button or hit Enter key to initiate the analysis process.

Our tool will fetch the necessary information, analyze the HTTP response headers, and provide you with clear information on whether the URL can be embedded in an iframe or not.

What differentiates an iframed webpage from a regular one?

An iframed webpage is different from a regular webpage. The iframed webpage appears as a window or frame within the host webpage, allowing external content to be seamlessly integrated. This integration provides a way to display content from different sources while keeping them separate from the host web page’s layout and functionality.
