Google Chrome will get lazy loading for video and audio elements

Google Chrome Boosts Performance: Lazy Loading for Video & Audio Arrives

The web is getting faster, and Google Chrome is leading the charge with a significant enhancement to its loading capabilities. Lazy loading, a well-established performance optimization technique, is expanding its reach within Chrome to encompass video and audio elements. This means users can expect quicker initial page loads and a more responsive browsing experience, especially on content-rich websites.

For years, lazy loading has been a cornerstone of efficient web design, prioritizing the loading of essential content first. This strategy ensures that users can begin interacting with a webpage almost immediately, without waiting for less critical, resource-intensive elements to download.

Since 2019, Chrome and other Chromium-based browsers have effectively implemented lazy loading for images and iframes. This intelligent approach delays the loading of these elements until they are within the user's viewport, preventing unnecessary bandwidth consumption and speeding up the initial rendering of the page.

Now, Google is taking this a step further. The company has revealed that it's actively testing an expansion of lazy loading to include video and audio elements. This update targets multimedia content embedded within standard <video> and <audio> HTML tags. While perhaps not as ubiquitous as images or iframes on every webpage, these media elements play a crucial role in modern web content delivery.

This performance boost is slated for arrival in Chrome 148, benefiting both desktop and mobile users. Given Google's commitment to integrating these improvements into the core Chromium codebase, it's highly probable that other popular Chromium-based browsers, such as Microsoft Edge, will also adopt this enhanced lazy loading functionality. This signifies a broader industry trend towards optimizing web content delivery for a smoother user journey.
