Accessible image embeds

Why Responsive Embeds Matter
A fixed-width video or image can overflow its container on smaller screens, forcing horizontal scrolling and breaking your layout. Embeds with hard-coded dimensions also shift the page as they load, which hurts Cumulative Layout Shift, one of Google's Core Web Vitals. This tool wraps every embed in an aspect-ratio container so it scales with the screen and reserves its space before it loads.

An iframe is one type of embed: it loads content from another site (like YouTube) inside a framed box on your page. Embed code is the broader term for any HTML snippet you paste to display external or media content, whether that is an iframe, an image tag, or a video tag. This tool generates the right one for what you are embedding.
-
The most common causes are a missing or mistyped URL, the source platform blocking embedding, or your CMS stripping the HTML. Paste the full code into a raw HTML or custom-code block (not the visual editor), and make sure the video or image URL is public.
