What the author says it does

Speed up your website using our ease image optimizer by serving WebP and AVIF images. By replacing files in standard JPEG, PNG and GIF formats with WebP and AVIF formats, you can save over a half of the page weight without losing quality.

After installing the plugin, you can optimize your entire Media Library with a single click — no further action required. When image optimization finishes, every visitor will automatically receive new images with significantly reduced file sizes.

As of today, over 95% of users use browsers that support the WebP format. The loading time of your website depends to a large extent on its weight and the level of image optimization. Using our WebP Converter, now you can and speed up it in a few seconds without much effort!

This will be a profit both for your users who will not have to download so much data, but also for a server that will be less loaded. Remember that a better optimized website also affects your Google ranking. Image optimization is very important.

AVIF support

Now in the PRO version you can use AVIF as the output format for your images. The AVIF format is a new extension — is the successor to WebP. Images converted to the AVIF format weigh about 50% less than images converted only to the WebP format, while maintaining better image quality.
