How we optimized YouTube iframes for better performance

Embedding YouTube videos with a regular iframe can significantly slow down page load.
A standard iframe loads heavy scripts and assets from YouTube even if the user never plays the video.

The solution

We built a custom Lite YouTube Iframe Component using React/Next.js.
Instead of rendering the iframe immediately, we first display the video’s thumbnail with a play button.

• When the user clicks the thumbnail, we replace it with the iframe.
• While the iframe is loading, we show a loading spinner for better feedback.
• If an error occurs, we safely fall back to the thumbnail.

Benefits

• Faster initial page loads (especially important when multiple videos are embedded).
• Lower resource usage (CPU & memory).
• Better user experience (lightweight thumbnails instead of heavy iframes).

Conclusion

By creating a simple and efficient Lite YouTube Iframe Component, we improved performance and delivered a faster, cleaner experience for users.
