<h4>Why use this plugin?</h4>
Over time, WordPress sites accumulate post meta data from plugins, themes, and page builders. When you switch or remove plugins, their meta often stays in the database — bloating tables, slowing queries, and making backups larger. Post Meta Editor and Cleaner gives you direct control over this data.
<h4>Key benefits</h4>
<ul>
<li>Database optimization — Remove orphaned meta from deleted plugins to reduce database size and improve performance.</li>
<li>Source identification — See which plugin or theme created each meta key. The built-in source map recognizes 50+ popular plugins (WooCommerce, Yoast, Rank Math, Elementor, Jetpack, WPML, and many more).</li>
<li>Bulk delete — Delete more meta keys at once. Adjust process speed to avoid timeouts on large sites.</li>
<li>Search and replace — Update URLs, domain names, or text across all posts. Works with serialized data (arrays, objects) — both values and keys can be updated.</li>
<li>Flexible deletion — Delete the entire meta key and its values, or clear values only while keeping the key structure.</li>
<li>Safe editing — Overwrite meta values in bulk, or perform targeted search-and-replace. Ideal for migrations, domain changes, or fixing incorrect product data.</li>
</ul>
<h4>What you can do</h4>
<ul>
<li>Clean up after removing plugins or themes.</li>
<li>Migrate a site and update old URLs in meta fields.</li>
<li>Fix WooCommerce product attributes, SEO meta, or custom fields in bulk.</li>
<li>Identify and remove unused or duplicate meta keys.</li>
<li>Reduce <code>wp_postmeta</code> table size for faster backups and queries.</li>
</ul>
<h4>Important</h4>
Before making any changes, create a backup, as modifications and deletions can only be restored from a backup.

Just Custom Fields adds ability to extend your Posts, Pages (and other custom post types) and Taxonomies with additional fields. After installation, you will see a simple settings page, which is self-explanatory to use. 
We use the standard WordPress PostMeta API and TaxonomyMeta API to save fields data, so you can use standard WordPress functions in your themes/plugins to get data.
IMPORTANT We do not recommend update plugins on your existing sites from version 2.* to version 3.0+. 
JCF v3.0+ is not compatible with versions 2.*, so some field settings can be lost (and as a result – wrong values on post edit pages).
Plugin supports such field types:
<ul>
<li>Input text</li>
<li>Select Box</li>
<li>Multiple Select Box</li>
<li>Checkbox (single and multiple)</li>
<li>Textarea (you can use WordPress editor too)</li>
<li>Datepicker</li>
<li>Simple Media (files and images upload)</li>
<li>Table</li>
<li>Fields Collection (repeatable fields groups)</li>
<li>Related Content (to set a relation to another Post/Page or Custom Post Type)</li>
</ul>
You can read full documentation on our site: http://justcustomfields.com.
For quick demo you can watch our presentation video:

Starting from v2.0 we have different options to save plugin configuration:
<ul>
<li>Ability to set Fields Settings global if you have MultiSite. So you can set them once, without copying all settings to every new site.</li>
<li>Ability to save Fields Settings to a file system (inside theme or wp-content folder). We expect this option will be popular among the developers. It will be much easier to move your fields’ settings between site versions (dev/production).</li>
</ul>
Starting from v2.2:
<ul>
<li>Simple Media field is now a single file only (before it was multiple). It uses new media upload box from WordPress and saves post thumbnail ID (before it was just a file url). So now you can use the get_the_post_thumbnail() function to work with attachments.</li>
<li>All fields now have “Shortcodes” and hints how to use them inside the templates for non-professional developers.</li>
</ul>
For easy migrations between different sites, we have Export/Import options.
