Most media cleaner plugins help you delete unused images. This plugin fixes a fundamental WordPress problem first.
WordPress has a built-in “Unattached” filter in the Media Library. The idea is simple: it shows you media files that aren’t connected to any post, so you can decide whether to keep or delete them.
The problem? WordPress only marks media as “attached” if it was uploaded directly through the post editor. Any image added through ACF fields, Gutenberg blocks, page builders, widgets, theme options, or shortcodes shows as “Unattached” — even though it’s actively being used on your site.
This makes WordPress’s native “Unattached” filter completely unreliable.
