Features

  • Loads images when they enter the viewport
  • Faster loading of store pages
  • Less server bandwidth usage
  • Works with the Google Lighthouse audit
  • Transparent, blurred or low-resolution placeholders
  • Configurable loading transitions
  • Supports remote (CDN) images

Overview

Lazy Load Ultimate offers a simple but efficient tool to optimize your site performance and improve the page loading speed of your Magento webshop.

Instead of preloading images when a page is opened, the extension delays the loading process until images enter the user's viewport or visible area of the webpage.

By loading images 'on demand', Lazy Load Ultimate makes your store pages load much faster, which will improve Google page ranking and reduce your server's bandwidth usage at the same time.

Various placeholders and loading effects#

Instead of using a generic placeholder image like other comparable plugins, Lazy Load Ultimate can show a transparent, blurred or low resolution placeholder when loading images.

By default the transparent placeholder is used which is great for improving your Google Lighthouse results. The extension's blur effect shows a smooth loading transition from blurred placeholder to focused full-size image, while the low resolution placeholder can be shown as blurred or pixelated.

Better webshop performance#

Lazy Load Ultimate is optimized for the Google Lighthouse auditing tool, which improves the performance of your store pages and consequently the page ranking of your Magento webshop in Google as well.
