Export/Import Media helps you move media between WordPress sites using CSV while preserving core media metadata columns such as alt text, title, caption, and description.
The free workflow is built for straightforward media export and import. The plugin generates a CSV file containing useful media information such as URLs, relative paths, alt text, titles, captions, and descriptions. You can validate that CSV, preview it before importing, and process rows in batches from a cleaner admin screen focused on the core workflow.
During normal free imports, detected duplicates are skipped to help prevent duplicate attachments in the library. Metadata columns are supported for rows that are imported, while controlled matching and update rules for already-existing media are handled by the separate Pro add-on.
Why use this plugin? 
* Straightforward CSV workflows: Export media data, validate incoming CSV files, preview them, and import them in batches. 
* Batch import: AJAX-powered processing helps avoid browser and timeout issues on medium and large imports. 
* Duplicate prevention: Detects existing matches and skips them in the normal free workflow. 
* Metadata columns: Supports title, alt text, caption, and description columns in CSV import/export. 
* Developer friendly: Includes hooks and filters for extending CSV columns, validation, admin UI, and import/export behavior.
Need more control for larger libraries? The separate Export/Import Media Pro add-on adds rollback restore points before imports, image conversion to WebP/AVIF where supported, saved workflows, background processing, controlled matching, metadata updates, and replace-file workflows.
