Google Chrome has made its lazy-loading feature much more efficient than what it was when first turned out last year. Lazy loading feature allows you to save data as it loads images on the site just when you are going to see them. The distance-from-perspective threshold has now been decreased to 1250px from 3000px for fast connections (e.g 4G), and to 2500px from 4000px on slower connections (e.g 3G).
Google Engineering Manager Addy Osmani composed on his blog about the change, saying that the new thresholds will offer much better data-savings now. The changes have been backported to users of ongoing versions of Google Chrome (79-85), so that they can benefit of the latest update.
Instead of loading all images as soon as you open a website page, Google Chrome lazy loading loads the substance just when you scroll and have it in see. Until you scroll down, the picture won’t load. This saves data, and furthermore saves on delays in the underlying website start ups. It is prescribed Web developers to abstain from setting lazy-loading for images visible in the first viewport, and to include it for the positions underneath.
Google Chrome will currently also support the lazy loading of iframe content. By using lazy loading, outsider embeds like Spotify widgets and YouTube videos will be visible just when the users scroll down to it, saving data and increasing the speed of the underlying site page loading time.
