Google is finalizing a technical improvement in Chrome, which will directly affect how videos and audio load on the web.Starting with version 148, the browser will natively enable the lazy loading of these elements, a new feature designed to lighten pages and reduce resource consumption, both on computers and mobile devices.
This feature expands on a capability that the Chromium ecosystem has been using since 2019 with images and iframes using the well-known "lazy loading" systemNow, that same logic will also be applied to multimedia content embedded in tags. and This is especially relevant at a time when many websites in Spain and the rest of Europe rely heavily on clips, embedded podcasts, and their own players.
What does it mean when Chrome delays loading videos and audio?
In practice, lazy loading means that the browser It does not download or initialize the heaviest elements until they are close to the visible area of ​​the screen.In other words, if a news article or report includes several players scattered throughout the text, Chrome will only focus on those near the user's current position, leaving the rest for later.
Until now, that intelligence was reserved for images and iframes, but The video and audio files would start loading as soon as the page opened.even if they were far below the first scroll and the reader never saw them. This situation could increase data traffic and lengthen initial loading times on congested mobile or home connections.
With the arrival of Chrome 148, Google will integrate native support for developers simply add the attribute loading=»lazy» to the labels andThe browser will automatically decide when it makes sense to fetch each resource, coordinating the download with the rest of the page elements.
According to the company's own documentation, the implementation will be global on desktop, Android, iOS and WebViewso that applications and sites that rely on web views can also benefit from this optimization without deep changes to their code.
Practical advantages for users: less data, less RAM, and faster pages
The main consequence of this change is that Many pages will open faster as the initial workload of the browser is reduced.Instead of downloading all embedded videos and audio at once, Chrome will prioritize text, key images, and content that is actually visible on the first screen.
This behavior directly affects those who browse from their mobile phones or with limited data plans, since Avoid unnecessary downloads of clips that may never be played.News sites, technology blogs, media websites, and portals with integrated video or podcast sections will especially notice the improvement when the number of multimedia elements on a single page is high.
Another important point concerns memory and CPU. By spacing out the initialization of media players and streams, The browser can better distribute the workload and reduce RAM usage spikes.This translates into smoother browsing with less lag on modest or older laptops.
Google explains that the native implementation will also allow Chrome Consider network quality, coordinate load with attributes such as preload y autoplay and avoid blocking key events such as window.onload with media that are not even close to the visible part of the page.
This isn't a visually striking feature, but it is one of those quiet improvements that They can make the website feel faster on a daily basis.especially in contexts where heavy resources are abundant and connections are not perfect.
What's changing for developers: Goodbye to many lazy-loading scripts
Until now, those who wanted to delay the loading of videos or audio usually resorted to JavaScript-based solutions, often combining Intersection Observer with dynamic attribute handling src o preloadIt was a valid approach, but it added complexity, increased maintenance, and didn't always fit well with the browser's internal heuristics.
With native support in Chrome 148, the scenario changes significantly: It will be enough to use the attribute loading=»lazy» directly in andThis is similar to how it's been done for years with images and iframes. The Chromium engine will handle the rest, without the need for external libraries or additional logic to control the exact moment of the download.
This move allows Chrome to more consistently optimize preloading and resource scanningThis is often complicated when the responsibility lies with third-party scripts. By being integrated into the platform itself, the browser can better decide what to download first, how to fit it into the cache, and what impact each file will have on the user experience.
Furthermore, the native approach reduces the risk of inconsistent configurations across sites, since The same lazy loading API applies to various types of elements (images, iframes, video, and audio).Many development teams in Europe that already use lazy loading in images will be able to extend the same logic to their multimedia content with minimal changes.
Which versions of Chrome will receive it and when will it arrive in other browsers?
According to the roadmap published in the Chrome platform status, Testing of this capability began in the Chrome 147 development branchAfter that initial phase, the company has set the stable release date for Chrome 148, a version that will be deployed on desktop as well as on Android, iOS and WebView environments.
This means that, barring any schedule delays, Native lazy loading for video and audio should be enabled by default for most users throughout the Chrome 148 lifecycleGoogle indicates that the change will be made transparently, without the user having to touch advanced settings or activate experimental flags.
As with almost everything integrated into Chromium, The improvement will not stop at just Google ChromeBrowsers such as Microsoft Edge, Opera, Brave, and Vivaldi, which are also very popular among European users, will benefit from the same support as soon as they adopt the version of the engine that includes this new feature.
In some cases, manufacturers will be able to decide whether to activate the default behavior or adjust it to their own policies, but Logically, most will follow the path laid out by Google., since it is a natural extension of an API they already use for images and iframes.
Impact on the current web and the Chromium ecosystem in Europe
Chrome remains the dominant browser globally and also in Spain, where It accounts for around two-thirds of usage compared to alternatives like Safari, Edge, or Firefox.As it is the de facto standard, every adjustment to its engine ends up influencing the behavior of a huge part of the web and the way many pages are designed.
In a context where news sites with their own video, training portals with streaming classes, and media outlets that integrate podcasts and embedded audio abound, The way these resources are managed has a direct impact on the reading experienceExcessive simultaneous downloads can slow down access to key information, especially on mobile connections outside of major cities or on shared networks.
The arrival of native lazy loading for video and audio fits with Google's strategy of to continue refining the browser's underlying features without necessarily changing its external appearance.These are improvements that may go unnoticed at first glance, but which, when combined, allow the first contact with a page to be faster and less burdensome for the connection.
At the same time, this move reinforces the idea that Chromium continues to evolve as a common base for many of the browsers used in EuropeAlthough many users opt for alternatives focused on privacy or personalization, many of these options almost automatically inherit optimizations such as the one now being introduced for audiovisual media.
With this change, the ecosystem gains an additional tool to contain the impact of multimedia content on daily browsing, reducing data consumption, shortening loading times and relieving pressure on less powerful devices without the user having to do anything special.
The addition of native lazy loading for videos and audio in Chrome 148 is shaping up to be A seemingly subtle improvement, but with tangible effects on the actual performance of many websites.: fewer resources downloaded at once, pages that respond faster, and smarter management of multimedia content across the entire Chromium ecosystem, from Spain to the rest of Europe.
