* Hi [@rrrfer](https://wordpress.org/support/users/rrrfer/)!
I can confirm that
HTML is actually minified as shown in the screenshots linked below.[https://ibb.co/xK3P0J9r](https://ibb.co/xK3P0J9r)
and [https://ibb.co/0RxdJXMY](https://ibb.co/0RxdJXMY)
* It’ll also help to know that WPO’s HTML minification feature works by removing
unnecessary characters from your site’s HTML output, applying GZip compression,
and then caching the page. That is why the feature requires the preload option
to be enabled, as that is the primary way to ensure proper minification.
* This process makes your HTML lighter, and its transfer faster when on site visits.
* Let us know if you have further concerns.
* Regards.
