The Media Cleaner checks your post types (posts, pages, portfolios, products, etc), your meta, widgets, theme, and resolves the shortcodes to find more. It also has specific checks to support the popular Page Builders (Pro Version). It will be easy to discover the broken media entries, unused media entries, files and orphan images (retina) in your system.
The result of this scan will be displayed on the dashboard of the Media Cleaner. From there, you can choose to move them in the trash. After testing your website thoroughly, you can empty this trash. Or you can Restore a media/file if it was actually in use, and mark it as Ignored by Media Cleaner.
Even if the plugin is stable and has its own trash system, please make a proper backup before using it (BlogVault is recommended). If you don’t really know what you are doing, simply do not do it.
The Pro Version
The Pro version adds Filesystem Analysis, extra support for complex plugins (page builders, especially), Live Site option and WP-CLI support.
With the Filesystem Analysis, Media Cleaner Pro scans your physical /uploads directory, and match it against the Media Library. It also has extra support for complex plugins, such as:
- ACF (+ ACF Widgets)
- Divi Builder
- Fusion Builder (Avada)
- Visual Composer (WPBakery)
- Beaver Builder
- Brizy Builder
- Oxygen Builder
- And more (Theme X, ZipList Recipe, UberMenu…)
The Live Site option will analyze the online version of your website, which might enhance the accuracy of the Cleaner in edge-cases.
Last but not least, Media Cleaner Pro has support for WP-CLI. If you have direct access (SSH) to your server, you will be able to run the plugin at a much higher speed or have it ran automatically, if you like.
