Google Chrome will launch a feature that speeds up page loading and saves network traffic

Brief about the new feature

Chromium-based browsers (Chrome, Edge, Vivaldi and others) will soon support *deferred* loading of media content – video and audio will be loaded only when the user scrolls to their position. This helps save bandwidth and speeds up rendering even on heavy sites.

What changed
Lazy loading was already available in Chrome but was limited to images and iframes. The new version allows videos and audio to load lazily. Sites typically use JavaScript (Intersection Observer) to determine media visibility. The browser now determines visibility itself without external code, reducing errors and simplifying page architecture.

Why it matters
* Bandwidth savings – files are loaded only when needed.

* Network quality awareness – the browser can adjust loading based on connection speed.

* Compatibility with autoplay – media starts automatically but does not block the rest of the page.

* A native approach eliminates third‑party scripts and improves interaction with the built‑in preloading scanner.

Development status
- Initial implementation steps were taken in January of this year.

- By the end of March, work moved to release preparation.

- The feature is now enabled “by default” for stable Chromium builds.

- It is expected to become available to the general public with the release of Chrome 148.

Thus, users of Chrome and other Chromium browsers will soon enjoy faster and more economical video and audio playback without unnecessary network requests.
