About This Service
Images are typically the largest assets on any webpage — and unoptimised images are the number one cause of slow websites. A single unoptimised hero image can add 3–5 seconds to page load time. At WebCraftera LLP, we perform comprehensive image optimisation: lossless and lossy compression using TinyPNG/Squoosh algorithms, conversion to WebP and AVIF formats (which are 25–50% smaller than JPEG), and implementation of responsive images with srcset so mobile devices download appropriately sized images.
We implement lazy loading for all below-the-fold images, set explicit width and height attributes to prevent Cumulative Layout Shift (CLS), and configure your CMS or CDN to automatically serve optimised formats to browsers that support them. The result is typically a 60–80% reduction in image data transfer.
