Iframe Embed Generator
Create iframe HTML with a sensible title, responsive width, loading behavior, optional sandbox restrictions and a live preview.
Loading a preview connects to the destination. Use a URL you trust. Permission changes reload an open preview.
<iframe
src="https://example.com/"
title="Embedded content"
style="border:0;display:block;width:100%;aspect-ratio:16 / 9;height:auto;"
loading="lazy"
referrerpolicy="strict-origin-when-cross-origin"
allow="fullscreen"
allowfullscreen
></iframe>Generate iframe code that is easier to ship
An iframe generator is most useful when it does more than print <iframe src="...">. The generated markup on this page includes an accessible title, a responsive width, a referrer policy and explicit loading behavior. You can add sandbox restrictions or fullscreen only when the embedded experience needs them.
Start with the destination's official embed URL
Many providers expose a dedicated embed endpoint rather than allowing their normal website pages to be framed. Maps, video players and dashboards often use a special URL format. If a service documents an embed URL, use that instead of assuming its public website can be loaded directly.
Use sandbox deliberately
The sandbox attribute starts from a restrictive environment and restores capabilities with tokens. It can be valuable for untrusted or semi-trusted content, but it should not be copied mechanically. Test the exact permissions the embed needs with the iframe sandbox tester.
Test the generated iframe
Generated markup cannot grant permission that the destination has denied. Run the URL through the iframe tester or the dedicated framing-header checker before publishing.

Common questions
How do I create responsive iframe code?
Use width=100% so the frame follows its container, then choose a sensible fixed height or place the iframe inside a responsive aspect-ratio wrapper when the content has a predictable ratio.
What should I put in the iframe title attribute?
Describe the purpose of the embedded content, for example 'Store location map' or 'Product demo video'. Avoid titles such as 'iframe' that do not help users understand the frame.
Does generating iframe code guarantee the website can be embedded?
No. The destination can still block framing through X-Frame-Options, CSP frame-ancestors, authentication or other browser behavior. Test the URL separately before relying on the embed.
