What is WP-Optimize plugin?
WP-Optimize is a WordPress plugin from UpdraftPlus Ltd. — the same team behind the popular UpdraftPlus backup plugin. Its main purpose is database optimization and cleanup, which it does well. In addition to database management, WP-Optimize includes page caching, image optimization, and minification features, making it a broader performance tool than it was when it launched primarily as a database cleaner.
The database optimization features are thorough: remove post revisions, spam comments, trashed content, transients, orphaned metadata, and other accumulated database bloat that slows queries over time. These operations can be scheduled to run automatically. For sites that have been running for several years without database maintenance, WP-Optimize can meaningfully reduce database size and improve query performance.
The page caching feature is functional for basic needs. Image optimization via compression (lossy or lossless) is handled through UpdraftPlus’s Shortpixel-powered cloud compression service with limited free quota and paid plans for higher volume. The combination of database cleanup, caching, and image optimization in one plugin from a trusted developer with a long track record makes WP-Optimize a practical all-in-one lite solution, though individual specialists (WP Rocket for caching, ShortPixel for images) outperform it in their respective areas.

Common Problems & Fixes
Why is WP-Optimize database optimization removing data I want to keep?
WP-Optimize’s database cleanup options include items like post revisions (which you may want for content recovery), pending comments, and some transients used by plugins. Always back up your database before running optimization. Preview what will be removed before confirming, and selectively disable any cleanup options that target data you want to preserve.
Why is WP-Optimize caching not showing improvements?
WP-Optimize page caching is functional but basic. If you are not seeing improvements, verify caching is enabled in WP-Optimize → Cache and that the cache directory is writable. Also check that no other caching plugin is active simultaneously. For more significant performance gains, consider a dedicated caching plugin alongside WP-Optimize’s database and image optimization features.
Why is WP-Optimize image compression failing or timing out?
WP-Optimize image compression uses an external cloud API. Failures usually mean the API quota has been reached (free tier has a limit) or the server cannot reach the API endpoint. Check WP-Optimize → Images → Compression Status for quota information. If network connectivity is the issue, verify your server can make outbound HTTPS requests to the compression API URL.
Customization & Developer Notes
How do I schedule automatic database cleanup with WP-Optimize?
Go to WP-Optimize → Database → Settings → Schedule and enable automatic optimization. You can set the frequency (daily, weekly, fortnightly) and which cleanup operations to include in each scheduled run. Scheduled cleanup runs through WP-Cron — ensure WP-Cron is functioning correctly on your hosting.
Can WP-Optimize run safely on a WooCommerce database?
Yes, with care. WP-Optimize can safely remove post revisions, spam comments, and some transients from WooCommerce databases. Avoid removing order data or WooCommerce-specific custom tables. Preview the optimization before applying and always back up the database first on stores with live orders.
Frequently Asked Questions
Is WP-Optimize from the UpdraftPlus team?
Yes. WP-Optimize is developed by UpdraftPlus Ltd., the same company behind the UpdraftPlus backup plugin. This shared lineage means reliability and long-term maintenance are reasonable to expect.
Can I use WP-Optimize alongside UpdraftPlus?
Yes. The two plugins are designed to work together. Run a fresh UpdraftPlus backup before using WP-Optimize to optimize the database, so you have a restoration point if anything needs to be rolled back.
Is WP-Optimize good for database maintenance on aging WordPress sites?
Yes. Sites that have been running for several years often accumulate significant database bloat from revisions, transients, and deleted content. WP-Optimize’s database cleanup is well-suited to this use case and the scheduled maintenance option keeps the database clean going forward.
Does WP-Optimize support WordPress Multisite?
Yes. WP-Optimize supports Multisite installations and can optimize databases across subsites. Premium plans include centralized multi-network management for managing optimization across multiple WordPress installations.
