Optipage is an extension to improve store page speed rank. It can minify page code, convert images to webp, fix some image tag attributes, lazy load images.
Compatible with OpenCart 3.x versions.

Features
    - Minify HTML code, inline JS scripts and CSS styles as well as JS and CSS files.
    - Convert JPG/PNG to WebP.
    - Fix image tag attributes (alt, title, width, height).
    - Image lazy loading.
    - Does not modify system files (OC Events System).

Disclaimer
The extension has been tested with the default OpenCart structure and theme, but third-party themes or extensions may cause incompatibilities and may require additional tweaking to fix this. The developer is not responsible for this and is not obliged to fix it, but can do so for an additional fee, which is discussed separately.
