Theia Upload Cleaner for WordPress

Theia Upload Cleaner for WordPress

Over time, WordPress sites can greatly grow in size due to file uploads that are left unused. These can be safely removed with Theia Upload Cleaner, a plugin that deep-scans your entire database to check for any files that are not referenced any more in any page, post, 3rd-party plugin or the media library. Most of these files are images and their associated thumbnails. Before a clean-up, a backup is always made so that you can safely check your website to ensure everything is working properly.

Note that it is always recommended to make a full backup of your own before running a clean-up, just in case.

Theia Upload Cleaner has two key-features:

  • The deep-scanning algorithm that searches your entire database for any reference to your files, regardless of the format its stored in: plain-text, serialized objects, or JSON objects. This ensures that all references are properly found and only unnecessary files are cleaned.
  • The automatic backups that give you complete peace of mind. Files are never actually removed during clean-up, but instead they are moved to a backup location. You can always verify that your site is running properly and no needed files were affected. Afterwards, the backups can be easily removed to gain more space.


  • Safely cleans your Uploads folder.
  • Move your unused media library items to the trash so you can review them.
