Bulk Optimize

Scan the Media Library and process eligible images through the safe batch queue.

Bulk Optimize processes existing Media Library attachments in small batches.

Typical workflow

  1. Open Bulk Optimize.
  2. Scan the library.
  3. Start the queue.
  4. Pause or resume as needed.
  5. Review optimized, skipped, and failed counters.
  6. Retry failed jobs after fixing the cause.

Eligible files

The queue uses the same source eligibility rules as upload automation and manual actions. JPEG, PNG, and WebP sources are supported. SVG, GIF, unreadable files, excluded MIME types, and files outside size or pattern rules are skipped.

Batch safety

The queue works in AJAX batches so large libraries do not require one long-running request. Default batch size is controlled by the VACIMG_QUEUE_BATCH_SIZE constant.
