Free Online iFrame Generator

1. Paste the URL you want to embed into the source field.
2. Set width, height, border, scrolling and fullscreen options.
3. Preview the embedded page live (if the site allows framing).
4. Copy the generated iframe tag into your HTML.

The iframe element, defined by the WHATWG HTML Living Standard, embeds one browsing context inside another — a page within a page. It is the standard way to drop in a map, a video player, a payment widget or a third-party form without rebuilding it yourself.

This generator assembles the tag from your inputs: the src URL, width and height (in pixels or percentages), a frameborder toggle, scrolling behavior and the allowfullscreen attribute for media players. As you change options the generated markup and the live preview both update.

Note a key constraint: a destination site can refuse to be framed by sending the X-Frame-Options header or a frame-ancestors directive in its Content-Security-Policy, which is why some previews stay blank even though the tag is correct. For responsive embeds, set width to a percentage or wrap the iframe in an aspect-ratio container. The tag is built entirely in your browser.
