If necessary, you can set a value for the number of images that should be preloaded when a user first opens a catalogue page.
The Magento 2 page speed optimizer module offers 2 options for the loading strategy – jQuerry Lazy Script or Native JS Lazy Script. Besides, it is possible to configure the lazy load function for each webpage type individually. Thus, with the extension, you get flexible settings for optimizing images on the homepage, category, product, and CMS pages separately.
Furthermore, to make page loading even faster, the Magento 2 Lazy Load extension can create copies of an image in different resolutions. The image resize function allows creating variants of the same picture in smaller sizes suitable for mobile and tablet devices.
Another valuable function available with the Amasty Lazy Load extension is related to the compression of images. The Magento 2 module automatically reduces the size of web store pictures without losing their quality. The extension supports gif, jpeg, and png formats that are the most widely used for images.
Besides, store owners can enable creating copies of images in the WebP format to make them smaller and automatically adjust the resolution. Images converted to WebP significantly increase a page loading speed and improve website positions in SERP.
The Magento 2 speed optimization module also allows users to leverage bulk image optimization. By default, all images saved in the catalogue and WYSIWYG folders are automatically processed and moved to the cache on a page load. If necessary, you can select other folders with your website pictures that should be optimized, as well as set the level of jpeg files compression and apply it to specific folders.
In addition to compressing images, the Magento 2 Lazy Load extension provides tools for optimizing code structure on a web store. One of the module’s features related to code compression is the minification of HTML, CSS, and JS files.

It allows reducing the size by 10 – 20% with no negative impact on the code itself.
As for some other advanced features offered by the Amasty Lazy Load extension, they include asynchronous indexing of the order data, automatic update of cached values by signing static files, and flat tables used for storing product and category info in the database.
