HTML Iframe Generator
Generate an <iframe> — set the source URL, title, size, and loading/referrer/fullscreen options, then copy the ready-to-use HTML. Free, instant, no AI involved.
Input
Required for accessibility; a sensible default is used if left blank.
Settings
Add custom CSS classes to the element. Separate multiple classes with spaces.
Output
Guides
Build a ready-to-paste <iframe> — set the source URL, an accessible title, size, and loading/referrer/fullscreen options, then copy the generated HTML.
Runs entirely in your browser: no AI call, no credits, no network round-trip. The output updates instantly as you type.
How to use it
- Set the Source URL (required) and a Title — every iframe needs one for accessibility; leave it blank and "Embedded content" is used.
- Adjust loading behavior, referrer policy, fullscreen permission, and size in Settings.
- Copy or download the generated HTML.
Why is there no live preview?
The output is real, unsanitized markup, and embedding an arbitrary third-party URL directly on this page isn't safe. Paste the code into your own page to see it in context.
