At Bits Kingdom, we know a fast website isn’t just nice — it’s non-negotiable. Page speed impacts everything: bounce rates, user satisfaction, SEO, conversions… the list goes on.
That’s why today’s tip is all about one of the easiest (yet most effective) speed upgrades you can make: lazy loading images.
What Is Lazy Loading — and Why Should You Care?
Lazy loading is a technique that delays loading images until they’re just about to enter the browser’s viewport. That means your page doesn’t waste time or bandwidth loading assets the user might never scroll down to see.
The result? Faster page loads, reduced initial payload, and a better user experience.
And the best part? It’s now a native browser feature. You can lazy load images simply by adding one attribute:
<img source="image.jpg" alt="bits tips image" loading="lazy"></img>That’s it. No libraries. No hacks. Modern browsers like Chrome, Firefox, Edge, and Safari (as of v16.4) all support it natively.
Got Tons of Images? Automate It with JavaScript
If you’re working with dynamically loaded content or a legacy site with lots of <img> tags missing the loading="lazy" attribute, a little JavaScript can help:
document.addEventListener("DOMContentLoaded", () => {
const images = document.querySelectorAll("img:not([loading])");
images.forEach((img) => {
img.setAttribute("loading", "lazy");
});
});This simple script adds the lazy loading attribute to any image that doesn’t already have it. Super handy for bulk updates or CMS-generated content.
Pro Tip: Don’t Lazy Load Everything
While lazy loading is a great default, you should not lazy load images above the fold (like your site logo, banner, or hero image). These should load immediately to avoid layout shifts and blank content during initial render.
A good rule of thumb: Only lazy load images that appear below the fold.
