Ever wondered why your WordPress site takes up so much disk space?

Often, it’s because your WordPress site is quietly hoarding thousands of image files you’ve NEVER actually used.

Every time you upload a single image, WordPress automatically creates 5-10 different size variations, like thumbnails, medium, large, and custom theme sizes. Most of these variations never appear anywhere on your site. Not once.

A site with just 5,000 images can easily have 20,000+ unused image files. This wasted storage inflates your backup sizes, slows down migrations, and quietly drains your hosting budget every single month.

Now imagine if you could see exactly which image variations are taking up space for no reason and remove them safely in just a few clicks.

That’s exactly what WP Media Cleanup by Duplicator offers. WP Media Cleanup is a powerful new tool that lets you reclaim disk space by identifying unused media files and removing them quickly and easily.

That means faster backups, easier migrations, and lower hosting bills… all without risking your site’s images or spending days manually sorting through files.

Background Story – Why WP Media Cleanup?

If you’ve ever tried to clean up your WordPress media library manually, then you already know how frustrating the experience can be. You’re staring at thousands of files with names like image-150x150.jpg, image-300x300.jpg, and image-768x432.jpg.

You have absolutely no way to tell which ones are actually being used.

As someone who has managed several WordPress sites, I saw this problem over and over. In fact, I also get questions about this all the time from our readers.

Site owners were paying for extra storage. Backups were taking longer than necessary. Migrations were slower than they should be. And it was all because of unused image variations hiding in the media library.

That’s why my team at Duplicator built WP Media Cleanup.

Simply put, it’s the safest way to reclaim disk space on WordPress sites. It lets you identify unused image variations and remove them while keeping all your original files protected.

Get a Complete Picture of Your Unused Files

The problem with unused images isn’t that they exist… it’s that you can’t see which ones are safe to delete.

With one click, WP Media Cleanup scans every corner of your WordPress site. From your published content to your widgets, custom fields, and theme settings. It builds a map of which images are actually being used.

Then it cross-checks that map against your media library to show you exactly what’s sitting unused on your server.

The result? A clear, detailed report that tells you precisely which files are safe to delete. No more guessing. No more manually checking thousands of images. Just a straightforward answer to “what’s wasting my storage space”.

Clean Up Your Media Library Without Fear

Once WP Media Cleanup shows you what’s unused, the power is entirely in your hands. Delete everything at once if you want to reclaim space immediately. Or review files one by one if you prefer a more cautious approach.

Either way, your original images are completely protected. WP Media Cleanup targets only the size variations, like thumbnail-150x150.jpg, medium-300x300.jpg, and similar files that WordPress generated automatically. Your source files remain untouched.

For agencies and freelancers managing multiple sites, this control matters. You can clean up client sites confidently, knowing you’re not risking their content or making irreversible changes.

Delete Now, Restore Later If You Need To

Cleaning up your media library shouldn’t feel risky. That’s why WP Media Cleanup builds in a recovery system from day one.

When you delete image variations, they’re not deleted forever, but they’re backed up. The files move to a safe temporary location and stay there for 30 days (you can change this duration in settings).

Need to retrieve the images you’ve deleted? Whether it’s one file or everything you deleted, restoration only takes seconds.

This approach gives you the confidence to actually clean up your site. You’re not gambling with permanent deletion… you’re making reversible decisions that you can adjust as you go.

Automate Cleanup Across Multiple Sites with WP-CLI

If you’re managing dozens of client sites, clicking through WordPress dashboards for every cleanup task isn’t realistic. You need speed and automation.

WP Media Cleanup includes full WP-CLI support, letting you handle everything from the command line. Scan for unused files, delete them, restore backups, check storage stats… all without touching a browser.

Here’s a typical workflow:

# Find and review unused variations
wp media-cleanup find_unused --format=table

# Delete them with confirmation
wp media-cleanup delete_unused --yes

# Check statistics
wp media-cleanup stats

For agencies, this means you can integrate media cleanup into your existing maintenance workflows, run it across all client sites at once, and reclaim storage at scale without manual intervention.

Built by the Team Behind Duplicator

WP Media Cleanup is built by the same team behind Duplicator, the WordPress backup and migration plugin trusted by over 1,500,000 professionals for protecting and moving their WordPress sites.

For years, Duplicator has helped you create reliable backups and handle complex migrations with ease. We’ve seen firsthand how unused image variations inflate backup sizes and slow down migrations across thousands of sites.

Our mission has always been to make WordPress site management simpler, faster, and more reliable… whether you’re backing up, migrating, or maintaining your site.

That’s exactly why we built WP Media Cleanup. It’s another tool in your arsenal for keeping WordPress sites lean, fast, and cost-effective.

Reclaim Disk Space and Reduce Hosting Costs

Your media library might look manageable, but behind the scenes, WordPress has been creating multiple versions of every single image you’ve ever uploaded. Over time, those unused variations add up to serious storage waste.

When you back up your site or move it to a new host, all those unnecessary files come along for the ride. That means bigger backup files that take longer to create, slower site transfers, and wasted storage you’re paying for every month.

Whether you’re running a blog, an online store, or a business website, WP Media Cleanup helps you avoid hitting storage limits, reduce your hosting costs, and keep your site running efficiently without the bloat. For agencies managing client sites, those savings multiply across your entire portfolio.

Here’s all it takes to get started:

✅ Install WP Media Cleanup on your WordPress site
✅ Click “Scan” to analyze your media library
✅ Review the list of unused image variations
✅ Delete the unused media in bulk or individually
✅ Restore anything if needed from the 30-day backup

WP Media Cleanup is available now as part of our Duplicator Elite bundle, or you can purchase it separately starting at $29 per year for a single site. Setup takes minutes, and you’ll immediately see how much reclaimable space exists in your media library.

We’re truly building something special here, and this is only the beginning. If you have ideas on how we can make WP Media Cleanup even more helpful for your business, I’d love to hear from you.
