FAQ

How to use?

Just activate the plugin. Additional settings is not required.

What is lazy loadind?

Lazy loading is the strategy of loading resources as they are needed, rather than in advance. This approach frees up resources during the initial page load and avoids loading assets that are never used.
Images that are offscreen during the initial pageload are ideal candidates for this technique.

How To minimize content jumping or unpredictable behavior images before loading?

Add width and height attributes to image.

<img width="200" height="100" src="image.jpg">

How to lazyload a background image?

In case you want to lazyload a background image via a class you can do so by using the addClasses option:

<style>
        .bg-stage.lazyloaded {
            background-image: url(lazyloaded-bg.jpg);
        }
      </style>

      <div class="bg-stage lazyload">
        <!-- content -->
      </div>

403 in every png upload

nickdesignz February 17, 2022

This tool generates also a code which adds a src to your png, this source is a 403; src="//www.w3.org/2000/svg%22%20viewBox=%220%200%201228%20294%22%3E%3C/svg%3E" class="attachment-full size-full lazyload" Source is invalid which causes many 403 errors on your site. ALSO: It’s not necessary to link to another source on a third plattform. This is just slowing down your site. Don’t install!

Great Plugin for saving time

This plug-in will transform all your actual PNG media to WebP + automatically transform them in WebP when downloading new loud formats, in a beautiful manner. Simple in the presentation but powerful in the application. I recommend it a lot !

i love you
