Lightweight YouTube Previews

Updated this week

FlyingPress improves performance by replacing heavy YouTube iframe embeds with lightweight thumbnail previews. The full video iframe is loaded only when the user interacts with it.

How it works

  • YouTube iframes are replaced with a static preview (thumbnail + play button)

  • The actual iframe is loaded only on click

  • Our cloud optimizer fetches the YouTube thumbnail during page preloading or caching

  • The thumbnail is self-hosted and saved in: wp-content/cache/flying-press/

  • The best resolution is selected automatically based on the video

Benefits

  • Removes YouTube’s JavaScript and tracking from initial load

  • Reduces page weight and improves render time

  • Boosts Core Web Vitals, especially LCP and TTI

  • Keeps video functionality intact with a seamless play-on-click experience

Notes

  • Works automatically for all embeds from youtube.com and youtu.be

  • Self-hosted thumbnails ensure better privacy and faster load

  • No setup needed—it runs during cache generation
