This plugin provides the ability to migrate individual WordPress post data to another WordPress site. 
Specifically, it provides the following features that are not provided by the standard import and export tools provided by WordPress. 
1. The standard tool does not export images and other media data. Instead, the importer reads the image URL in the XML and attempts to re-download the file from a remote location. However, this requires that the import source site is public and the media file URL is accessible. If the site is local or private, the media download will fail and only an empty attachment post will be created. 
This plugin extracts images and other media data and WordPress database information and exports them together in a single ZIP file, eliminating such problems. 
2. The standard tool does not export revisions, but this plugin provides export and import functions. 
3. The standard tool allows you to select what to export for each post type, but not for each individual post. 
This plugin allows you to select what to export for each individual post.

<li>Database export with binary-safe hex encoding (preserves serialized PHP data)</li>
<li>Database import with streaming line-by-line parsing (handles large dumps)</li>
<li>File upload, download, archiving (tar.gz/zip), and extraction</li>
<li>Serialization-aware search-replace for domain migrations</li>
<li>Dual authentication: API key header or WordPress Application Passwords</li>
<li>WP-CLI detection (informational, reported in status endpoint)</li>
