Speedora is a free, all-in-one speed plugin. It caches pages, minifies HTML/CSS/JS, lazy-loads media, converts images to WebP, and removes unused WordPress baggage. Settings are grouped by feature, and child options stay locked until their parent is enabled. Do not run Speedora page cache together with another page-cache plugin (WP Super Cache, W3 Total Cache, LiteSpeed Cache, and similar). Use one page cache at a time.
