Frequently Asked Questions
What is an iframe?
An iframe is an HTML element that embeds another webpage or resource inside your page. It is commonly used for videos, maps, forms, and widgets.
How do I make an iframe responsive?
A common technique is wrapping the iframe in a container with a percentage-based padding (aspect ratio) and positioning the iframe absolutely. This tool can generate that markup automatically.
What is iframe sandbox and should I use it?
The sandbox attribute restricts what the embedded page can do. It improves security, but some embeds may require permissions like allow-scripts or allow-same-origin.
Does this tool support YouTube and Vimeo?
Yes. It can convert common YouTube and Vimeo URLs into the correct embed URLs automatically.
Is the iframe generator private?
Yes. Generation happens in your browser. We don’t store your URLs or generated code.
Can I use this code in WordPress or Webflow?
Yes. Copy the output HTML snippet and paste it into an HTML block or custom code section.
