Let’s face it. WordPress is awesome, but it can get messy. Especially when it comes to images. Over time, your media library fills up with unused images. Some of these are test images. Others are duplicates. And many are leftovers from deleted posts or themes. All of them take up space. Which slows down your site and clutters your dashboard. Time to clean things up!
Good news! You don’t have to do this by hand. There are some awesome plugins that help you bulk delete unused images quickly and safely. In this post, we’ll go over the best plugins for the job. Each one has its strengths. And we’ll keep things light and fun, so hang tight!
Why You Should Delete Unused Images
Here are a few simple reasons:
- Speed: Fewer images = faster backups, scans, and uploads.

Steps Before You Clean
