Media Alt Bulk Editor – WordPress Image SEO Utility

Media Alt Bulk Editor is a lightweight WordPress admin plugin for safely managing image ALT text, image titles and captions in bulk.

Safe Bulk Editing

This plugin is built around safety. Changes are applied only to selected rows. Before data is updated, the plugin records change history. Undo is performed at batch level and only restores values when the current value still matches the recorded new value. If the image metadata has already been changed by another user or another process, the undo action skips that value instead of overwriting it.

CSV Export

Export image metadata from the current filtered view. The export includes useful fields such as attachment ID, file name, file URL, MIME type, current ALT, title, caption, filename-based ALT candidate, WooCommerce image status, potentially unused status and modified date.

CSV Import With Preview

CSV import requires a header row and an attachment_id column. New values can be supplied with:

- new_alt
- new_title
- new_caption

Blank cells are treated as no change. To intentionally clear a value, use:

__EMPTY__

Before applying changes, the plugin displays a preview so you can review differences and apply only selected rows.

Filename ALT Suggestions

The plugin can generate simple ALT suggestions from file names by removing the extension, replacing hyphens and underscores with spaces, removing common size suffixes and formatting the text into a readable label.

This is not AI generation. The suggestions are shown for review and are not automatically applied unless you select rows and choose to fill selected empty ALT fields.

Potentially Unused Filter

The plugin includes a “Potentially unused” filter to help review images that may not be attached or referenced. This is a cautious helper filter only. It does not claim that an image is definitely unused, and it never deletes media files.

No image deletion, trash action or file deletion feature is included.

WooCommerce Product Image Filter

If WooCommerce is active, the plugin can filter images used as product thumbnails, product gallery images and variation images.

WooCommerce is optional. The plugin works normally without WooCommerce.
