You forget sandbox attributes. The aspect ratio breaks on mobile. It slows down your page load because it loads immediately.

I built a free tool that solves this.

  • Adds lazy loading automatically
  • Generates responsive aspect ratio wrappers

Use cases:

  • Embedding YouTube or Vimeo videos
  • Adding Google Maps to a page
  • Inserting secure external widgets
  • Building responsive dashboards

Privacy:
100% client-side. Nothing uploaded.
