Maira Foresto

Export/Import Media helps you move media between WordPress sites using CSV while keeping core media metadata such as alt text, title, caption, and description.
The plugin generates a CSV file containing useful media information such as URLs, relative paths, alt text, titles, captions, and descriptions. You can then validate that CSV, preview it, and import it in batches.
Why use this plugin? 
* Batch import: AJAX-powered processing helps avoid browser and timeout issues on medium and large imports. 
* Metadata aware: Supports title, alt text, caption, and description columns. 
* Developer friendly: Includes hooks and filters for extending CSV columns, validation, admin UI, and import/export behavior.
<h3>Features</h3>
<ul>
<li>CSV Export: Export media data to CSV with filters by date, media type, and attachment context.</li>
<li>CSV Preview: Validate and preview the file before importing.</li>
<li>Batch Processing: Import media rows in AJAX batches.</li>
<li>Local Import Mode: Register files that already exist in <code>/uploads/</code> without downloading them again.</li>
<li>Honor Relative Path: Reuse or preserve folder paths from the CSV.</li>
<li>Skip Thumbnail Generation: Speed up large imports when needed.</li>
<li>Duplicate Prevention: Uses source meta and file fingerprints to avoid importing the same media twice.</li>
<li>Downloadable Log: Save an import log as <code>.txt</code> after the process finishes.</li>
</ul>
