Post Media Cleanup

Post Media Cleanup removes orphaned media files from your server when you permanently delete a post.

When you permanently delete a post, this plugin automatically finds and removes:

• Featured image
• Images and files embedded in post content
• PDFs and any linked files in content
• All attachments uploaded directly to the post

Key Features

• Only fires on permanent deletion — moving to trash is always safe
• Skip Shared Media — never deletes a file used by another post
• Works per post type — configure exactly which types trigger cleanup
• Compatible with S3 and cloud storage
• Multisite ready
• Developer friendly — filter hooks to extend behaviour

For Developers

Add extra attachments to the deletion list:

add_filter( 'postmediaweb_attachment_ids_to_delete', function( $ids, $post_id ) {
    $extra = get_post_meta( $post_id, 'my_custom_pdf', true );
    if ( $extra ) $ids[] = (int) $extra;
    return $ids;
}, 10, 2 );

Prevent a specific attachment from being deleted:

add_filter( 'postmediaweb_should_delete_attachment', function( $should, $att_id, $post_id ) {
    if ( $att_id === 999 ) return false;
    return $should;
}, 10, 3 );
