7 Best WordPress Database Optimization Plugins

Every WordPress website has a unique database. It contains all of the information on your website, from user data to comments, posts, and more. As your site grows, so does its database, and in many cases, you’ll end up storing a lot of information well beyond the point that it’s useful. This can slow down your site unnecessarily.

In this article, we’ll introduce you to seven of the best WordPress database optimization plugins you can use to keep your site lean and fast. We’ve chosen them based on their performance, configuration options, ratings and reviews, and support from their developers.

Let’s get to it!

1. WP-Optimize

The WP-Optimize plugin

First on our list, WP-Optimize is an all-in-one WordPress optimization plugin. It includes tools to help you clean up your database, minify scripts, enable lazy loading, perform image optimization, and more.

If you’re using WP-Optimize for database optimization, you can choose what information the plugin will try to clean up. For example, you can configure it to clear out old post revisions, erase trashed posts, remove spam comments, and more:

Cleaning up your database using WP-Optimize

This plugin also lets you identify orphaned tables within your database and delete them manually.

However, one feature that is missing is the ability to create database backups before you run optimizations. WP-Optimize addresses that problem by integrating with the UpdraftPlus plugin. If you use UpdraftPlus as well, WP-Optimize includes settings that will automate database backups before you run a cleanup.

Key Features:

  • Choose what parts of your WordPress database to optimize
  • Identify and remove orphaned tables within the database
  • Configure your site’s caching settings
  • Enable lazy loading
  • Automate image optimization
  • Minify scripts on your website
  • Integrate the plugin with UpdraftPlus to take care of database backups

WP-Optimize is for you if…

…you want a plugin that doesn’t just help you optimize your database, but multiple aspects of your WordPress website. It’s also a solid pick if you’re already using UpdraftPlus.

Price: Free, with premium licenses starting at $39 per year | More Information

2. Advanced Database Cleaner

The Advanced Database Cleaner plugin

Advanced Database Cleaner gives you an overview of what elements you can safely remove from your database to keep it lean. You can also use it to delete tables and cron jobs from your website.

One standout feature this plugin offers is the option to ignore some of the most recent changes to your database when cleaning it up. You can tell the plugin to keep data from the last “X” days for each type of element it optimizes:

Configuring Advanced Database Cleaner to keep recent data

Advanced Database Cleaner also lets you schedule database optimization processes, and configure multiple tasks to run later on. For example, you can schedule the plugin to clean posts within your trash weekly, and have it delete post revisions on a monthly basis.

Key Features:

  • Remove unnecessary information from your database
  • Clean up tables and cron jobs
  • Exclude recent data from cleanups
  • Schedule multiple database cleanups in advance

Advanced Database Cleaner is for you if…

…you want a plugin that enables you to set up recurring database optimization processes. Plus, you get full control over what data you want to optimize and when, which makes this one of the best WordPress database optimization plugins for advanced users.

Price: Free, with premium licenses starting at $39 | More Information

3. Optimize Database After Deleting Revisions

Optimize Database After Deleting Revisions

Optimize Database After Deleting Revisions does much more than its name implies. By default, this plugin will help you delete revisions for all of the post types on your website. However, you can also configure it to help you optimize your database by deleting items in the trash, unused tags, spam content, and more:

Configuring which types of post revisions to delete

You can use this tool to configure scheduled optimizations, and it can also help you delete specific tables from your database. However, it doesn’t tell you which custom tables correspond to which plugins, which makes using that feature a bit risky unless you know what you’re doing.

Key Features:

  • Delete post revisions for all of your WordPress post types (or specific ones)
  • Preserve recent revisions
  • Configure how many revisions you want to keep for your posts
  • Schedule database optimizations
  • Delete specific tables from your database

Optimize Database After Deleting Revisions is for you if…

…you run a website with a hectic posting schedule. Post revisions can quickly add up if you publish a lot of content, and this plugin can help you optimize your database by keeping unnecessary revisions down to a minimum.

Price: Free | More Information

4. Plugins Garbage Collector

The Plugins Garbage Collector plugin

Most of us use lot of WordPress plugins. They’re one of the main reasons the platform is so popular, since they enable you to implement almost any feature you can imagine on your website. Throughout your site’s life cycle, you’re likely to phase out a lot of plugins as you find better options or simply stop needing them.

Much of this software leaves behind unused entries and tables in your database. Plugins Garbage Collector finds that orphaned data and deletes it. With this solution, you don’t get any advanced configuration settings – it just comes with one option to help you scan and clean your database quickly.

Key Features:

  • Find entries from unused plugins in your database and delete them

Plugins Garbage Collector is for you if…

…you like to experiment with a lot of plugins, and you’re worried about all the orphaned tables and entries they leave in your database. With this plugin, you can run a quick scan periodically and ensure that the plugins you delete don’t continue to have an impact on your website.

Price: Free | More Information

5. WP-Sweep

The WP-Sweep plugin

WP-Sweep enables you to optimize your WordPress database by “sweeping” everything from revisions to automatic drafts, deleted posts, spam comments, orphaned users, and more. As with many of the other best WordPress database optimization plugins, you can choose what data to clean up or to do a full sweep:

Doing a full database optimization sweep

One downside of using WP-Sweep is that it doesn’t enable you to select specific tables or elements to optimize automatically. Instead, you can either perform a complete sweep or clean up individual elements manually.

Key Features:

  • Clean specific types of elements from your database
  • Do a full “sweep” of your database and optimize all of its tables

WP-Sweep is for you if…

…you want a tool that enables you to perform one-click database optimization, and offers the option to clean up individual tables manually.

Price: Free | More Information

6. WP Reset

The WP Reset plugin

Sometimes, the best way to optimize your WordPress database is to start from scratch. If you want to re-launch your website and start over, you’ll need to clean up its database, which is precisely what WP Reset does:

Using the WP Reset plugin

With this plugin, you can wipe most of the information from your database, while preserving key elements such as your admin user account, basic site configuration (such as your WordPress address and indexing settings), plugins, and themes. In short, the plugin lets you delete all of the content from your site without overwriting your WordPress installation.

Key Features:

  • Reset your WordPress database
  • Preserve key data such as your admin user account

WP Reset is for you if…

…you want to start over with your website without re-installing WordPress, your plugins, and your themes.

Price: Free, with premium licenses starting at $7.50 per month | More Information

7. Database Backup for WordPress

The Database Backup for WordPress plugin

This last plugin is a little different. When you back up your WordPress website, you not only make a copy of its files but also of its database. Without a database backup, you’re liable to lose most of your website’s content if you have to restore it.

Moreover, if you’re planning to optimize your database by deleting some tables, it’s always a smart move to create a backup beforehand. That’s precisely what Database Backup for WordPress enables you to do:

Creating a database backup

It helps you back up your core WordPress tables (while excluding revisions and spam comments). However, you can also add custom tables to your backups, and set up a schedule that creates new copies periodically.

When it comes to storage, the plugin gives you the option of downloading your backup files directly or having them emailed to you. If you use its backup scheduling feature, you’ll receive those files via email.

Key Features:

  • Back up your WordPress database
  • Exclude post revisions and spam comments
  • Select which custom tables you want to include
  • Schedule backups
  • Download backup files to your computer, or configure the plugin to send them to an email address

Database Backup for WordPress is for you if…

…you plan on working directly with your database in any capacity. Altering your database manually or using a plugin to delete tables can wreak havoc on your website if you’re not sure what you’re doing. If you’re not already using a backup plugin that also saves your database, Database Backup for WordPress is a key tool to have on hand.

Price: Free | More Information


Using one of the best WordPress database optimization plugins can help you clean up a lot of the unused entries and data that accumulates as your website grows. If you’ve been working on your website for a while now, these tools should help you recover some storage space and perhaps even increase your site’s performance.

If you’re still not sure which plugin to use, WP-Optimize is a great all-around choice for most websites. Regardless of which solution you choose, we recommend that you also set up a backup solution such as Database Backup for WordPress.
