Overview

atec-WebP works automatically, no configuration required.
Just install, activate and switch on the “WebP active” option. That’s all.

Most other image optimization plugins (such as Smush or LiteSpeed) use batch conversion.
These plugins convert ALL images in the upload folder, including thumbnails.
This is not necessary, as some of these images might never be requested.
atec-WebP works “on demand”, it converts images only when requested. This saves disk space.

In case you are using a CDN the rewrite rules to serve .webp files will not be effective – unless you exclude image files from caching.
Please check the response header to see whether .webp files are actually handled by your server – or delivered by a CDN.
