Pixellize Image Optimizer

About

Pixellize Image Optimizer is a free WordPress plugin that automatically converts every image you upload to WebP, so your pages load faster and score better on Core Web Vitals. No bulk jobs, no account, no API key, and no paid tier. It runs entirely on your own server. Version 0.4 lets you keep your originals or replace them to save space, restore any image in one click, converts every thumbnail size, and cleans up WebP files when you delete an image.
