Our Lazy Load Ultimate extension provides you with a simple but efficient tool to optimize your site performance and improve the loading speed of Magento store pages. Instead of slowing down the web shop by preloading images directly when a page is opened, our extension delays this process until the images enter the user's viewport (the visible area of a web page).

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


Extension Features

  • Speed up your store page loading speed by loading images 'on demand'
  • Delay image loading until they enter the user's viewport / visible area of a webpage
  • Improve your site performance and Google page ranking
  • Reduce your server's bandwidth usage
  • Show smooth loading transition from blurred placeholder to focused full-size image
  • Select the enabled store pages and layout handles, or exclude specific URLs and patterns
  • Configure the placeholder image quality and blur intensity
  • Set a preferred blur transition time and viewport trigger distance


Smooth Blur Effect Transition

Where other comparable plugins show generic placeholders or empty spaces when loading images, our lazy load extension distinguishes itself by using a smooth loading transition from blurred placeholder to the focused full-size image.

The placeholder image quality, blur intensity, transition time and viewport trigger distance can be easily configured in the back-end and the extension can be separately enabled for CMS pages, category pages, product pages, checkout pages, and selected layout handles.
