Images are the single biggest cause of slow websites. The right format, the right compression, the right delivery , done properly, image optimisation is one of the fastest performance wins available.
On most websites, images account for the majority of page weight. A single unoptimised hero image can add several seconds to your LCP score and cost you both rankings and sales.
THE WEIGHT
Unoptimised images are the leading cause of poor Largest Contentful Paint scores , the metric Google measures most closely for loading performance. Oversized files, wrong formats and missing dimensions all contribute. Fixing images is almost always the highest-return performance task on any site.
THE IMPACT
Google's research consistently shows that every second of load time reduces conversions. Images that load quickly don't just improve rankings , they reduce bounce rates and increase the chance a visitor stays long enough to become a customer.
Audit My ImagesThe core disciplines that make image optimisation work , each one contributing to better performance, rankings or conversions.
Serving WebP or AVIF instead of JPEG and PNG typically cuts file sizes by 30–80% with no visible quality loss.
Lossless and lossy compression tuned per image type, removing unnecessary data without degrading appearance.
Serving appropriately sized images per device using srcset and sizes , no 2000px images on a 375px phone.
Loading below-fold images only when they're about to enter the viewport, reducing initial page weight.
Setting explicit width and height on every image to prevent layout shifts (CLS) while loading.
Delivering images from a CDN close to the user and caching aggressively to reduce repeat load times.

Don't take our word for it , here's what the businesses we've worked with have to say.
The team at Swift Productions were prompt, professional and provided us with some great designs for our latest car audio flyer. I personally was surprised at the speedy delivery and communication throughout the entire process.
I engaged Swift Productions to desgin my ecommerce store about two months ago. During the time that I have worked with them, their communication has been nothing short of excellent.
Amazing service, we would definitely recommend Swift Productions. Danny and team were great, helped us create our Straw Belicious Shopify website.
They follow through the entire process of your listing templates 100%. Danny had been a magnificent employee who help me through the listing. He is wealth of knowledge.
Monica you've been amazing throughout the entire process. Turning stuff around on a dime and nothings ever been too much trouble.
I had such terrible service from my previous store designer would never answer me no communication whatsoever. So I had to look for someone else. I decided to change to Swift and have never been happier.
Over two decades of websites, strategy and growth, delivered.
WebP is the current best all-round format , it's supported by all modern browsers and typically 30–50% smaller than JPEG at equivalent quality. AVIF is even more efficient but slightly less widely supported. We assess browser support and serve the right format per device where needed.
Done properly, no. Lossless compression removes metadata and redundant data without touching pixels. Even lossy compression at appropriate settings is visually indistinguishable from the original while dramatically reducing file size.
Lazy loading delays loading images that are below the visible screen area until the user scrolls toward them. This reduces the initial page weight, improving load time and LCP without affecting anything the visitor can immediately see.
LCP , Largest Contentful Paint , is most commonly the hero image or a large above-fold graphic. If that image is large and unoptimised, it becomes the single biggest thing slowing your LCP score. Optimising it is usually the highest-impact single change you can make.
Yes. Both platforms have options for format conversion and compression, and we implement proper responsive image handling, lazy loading and CDN delivery on each. The approach varies by platform but the outcomes are the same.
Google Search Console's Core Web Vitals report will flag LCP issues. PageSpeed Insights identifies specific images causing problems. We run a full audit as part of our technical SEO and performance work and show you exactly which images are costing you speed.
Optimised images reduce page weight, improve loading times and preserve visual quality across mobile, desktop and high-resolution screens.
