Over time, your WordPress database accumulates a massive amount of unnecessary data—like post revisions, auto-drafts, orphaned metadata, and expired transients. This bloat slows down your site and increases your backup sizes.
Dejunk DB is a lightweight, intuitive, and highly secure tool designed to clean up this orphaned and duplicated data, optimizing your database for peak performance.
Before making any changes, Dejunk DB provides a built-in Backup Engine so you can safely create a snapshot of your database and download it locally.
🚀 Key Features
- Built-In Database Backups: Create, download, and manage secure
.sqlbackups of your database directly from the plugin dashboard before you clean. - Preview Before Dejunking: View the exact items (up to 500 records) that are flagged for deletion in a clean, AJAX-powered modal so you know exactly what is being removed.
- Post Data Cleanup: Safely remove Post Revisions, Auto Drafts, Trashed Posts, and Orphaned Post Meta.
- Comment Cleanup: Quickly delete Unapproved Comments.
- User & Term Cleanup: Clear out Orphaned User Meta and Orphaned Term Relationships.
- Options Cleanup: Flush stale and expired Transient Options (
_transient_and_site_transient_) that bloat thewp_optionstable. - Table Optimization: Run standard MySQL
OPTIMIZE TABLEcommands on all your WordPress tables with a single click. - Global “Dejunk Everything” Switch: A master switch to clean up all identified junk sections instantly.
- Clean Uninstall: When you uninstall Dejunk DB, it automatically cleans up its transients and securely deletes all backup files it created, leaving zero footprint.
Note: Any dejunking done to your database is irreversible. Please always utilize the built-in backup tool before running a cleanup.

FAQ
-
Is it safe to delete post revisions and orphaned meta?
-
Yes. Orphaned meta refers to data left behind when a post or user is deleted. Revisions are old versions of your posts. Removing them will not affect your live website content, but will significantly reduce database size.
-
Where are the database backups stored?
-
Backups are stored in your
wp-content/uploads/dejunk-db-backupsdirectory. The plugin automatically generates an.htaccessfile and anindex.phpfile inside this folder to block direct web access, keeping your backups secure. -
Can I restore a backup directly from the plugin?
-
For strict security compliance, automatic SQL restoration is not included in the plugin. To restore your database, simply download the
.sqlfile from the dashboard and import it using phpMyAdmin, WP-CLI, or your hosting control panel. -
Does Dejunk DB leave files behind if I uninstall it?
-
No. Dejunk DB hooks into the WordPress uninstall process. If you delete the plugin from the WordPress admin, it will automatically remove its generated backup folder and all
.sqlfiles to ensure no sensitive data is left behind. -
Why can I only view 500 items in the preview modal?
-
To prevent memory exhaustion and browser crashing on large sites that may have hundreds of thousands of junk rows, the preview query is intentionally limited to 500 items. The “Clean” action, however, will remove all of them.
