What’s Lazy Loading and the way to Enable It in Google Chrome 74

Google Chrome 74 is now readily available for download on all supported platforms, and likewise to some dark theme for Windows 10 (which is currently rolling out to devices in phases), it also introduces a number of other improvements and security fixes.

One under-the-hood addition that many users might not be conscious of is called lazy loading, and it is supposed to make page loading faster in the search engines Chrome.

What’s vital that you know, however, is the fact that lazy loading is still considered an experimental feature at this time, so it’s not enabled automatically in the search engines Chrome 74. There’s an opportunity that Chrome 75 would activate it for those users, as well as the moment, you have to turn it on manually in the browser.

“What is lazy loading?”

The concept of lazy loading isn’t necessarily new, but it’s the very first time Google causes it to be readily available for users running the stable version of Chrome browser.

In a few words, lazy loading allows the application to load only critical page content that you’ll require, and just then load additional resources when scrolling to them.

By doing this, the page actually loads faster and avoid unnecessary downloads and bandwidth use because, technically, a browser without lazy loading would virtually download all content even if you might not need or access it.

Google explains the following the developer documentation on lazy loading:

“Lazy loading is technique that defers loading of non-critical resources at page load time. Instead, these non-critical resources are loaded at the moment of need. When we lazy load images and video, we reduce initial page load time, initial page weight, and system resource usage, all of which have positive impacts on performance.

Combined with care, lazy loading images and video can seriously lower the initial load time and page payloads on your site. Users won’t incur unnecessary network activity and processing costs of media resources they may never see, however they can still view those resources when they want.

As far as performance improvement techniques go, lazy loading is fairly uncontroversial. If you have a lot of inline imagery in your site, it is a perfectly fine way to cut down on unnecessary downloads.”

“How to allow lazy loading in Google Chrome 74”

While it’s still an experimental feature, you are able to enable lazy loading in the latest stable form of Google Chrome and check out out yourselves to find out if any speed increase is noticed when loading sites.

Doing this is quite easy. First of all, launch the browser as well as in the address bar, type the next command:

chrome://flags

Then, you have to let the following two flags in the browser:

Enable lazy image loading
Enable lazy frame loading

To find then faster, you can copy the next codes and paste them within the address bar of Google Chrome:

chrome://flags/#enable-lazy-image-loading
chrome://flags/#enable-lazy-frame-loading

Both of these two flags are currently set to Default mode, which means they’re disabled, so just click the drop-down menu after which switch them to Enabled. Reboot your browser and the feature should technically be up and running inside your browser.

Keep in mind, however, that developers have to manually enable lazy loading on their websites, therefore it might take a while before the web is prepared for this new feature. However, you are able to already check out this feature in Chrome 74, albeit I expect this push to become extensively adopted when the next form of Chrome gets the green light.

Google Chrome 75 is projected to produce on June 4, as the first beta is going live between May 2 and could 9.
