What Gets Duplicated:

<li>All custom fields and metadata</li>
<li>Categories, tags, and custom taxonomies</li>

What Doesn’t Get Duplicated:
<ul>
<li>Comments (by design – prevents duplicate comment threads)</li>
<li>Post ID and GUID (new unique identifiers assigned)</li>
</ul>
How to Use:
<ol>
<li>Single Duplication: Hover over any post and click “Duplicate [Post Type]” in the row actions, or click the “Duplicate Post” button in the Gutenberg editor</li>
<li>Multiple Clones: In the duplication modal, click the copy icon to create multiple copies of a single post (up to 50 clones)</li>
<li>Bulk Duplication: Select multiple posts using checkboxes, choose “Duplicate” from the Bulk Actions dropdown, then configure each post individually</li>
<li>Customize Settings: Edit title, slug, status, author, date, post type, featured image, and parent for each duplicate</li>
<li>Configure Defaults: Go to Settings > Post Duplicator to set default status, author, date, and title/slug suffixes</li>
<li>Configure Post Types: Go to Settings > Post Duplicator > Post Types to control which post types can be duplicated and which appear in the “Post Type” dropdown menu</li>
</ol>
Default Settings:
The plugin works immediately with sensible defaults: 
* Duplicated posts are created as Drafts (prevents accidental publishing) 
* Title suffix: “Copy” 
* Slug suffix: “copy” 
* Author: Current User 
* Date: Current Time
All defaults can be customized in Settings > Post Duplicator.
Integration:
Post Duplicator works seamlessly with: 
* WPML and Polylang (multilingual support) 
* WooCommerce (excludes review counts automatically) 
* ACF (Advanced Custom Fields) – preserves all field data 
* WP Customer Area (special file duplication support) 
* All custom post types and taxonomies
Security:
<ul>
<li>Users without <code>publish_posts</code> capability cannot publish duplicates (forced to Pending)</li>
<li>Non-authors cannot duplicate unpublished posts from other users</li>
<li>Granular permission system controls who can duplicate posts</li>
<li>All data is sanitized and validated before duplication</li>
</ul>
Developer-Friendly:
Includes hooks and filters for easy customization: 
* <code>mtphr_post_duplicator_created</code> action 
* <code>mtphr_post_duplicator_meta_{$key}_enabled</code> filter 
* <code>mtphr_post_duplicator_meta_value</code> filter

Post Duplicator


so basic that i would miss this in core.



great support either!


Just great.


Much better than Yoast Post Duplicate and Page Duplicate plugins. It is a shame this plugin seems to be burried. It works better, and follows admin setting guidelines. And best of all, it does not have any obstrusive pro money swindling practices.



This is how a plugin should be made!


Perfect!

Creates functionality to duplicate any and all post types, including taxonomies & custom fields. Perfect for developers and content creators.
