100% LOCAL PIPELINE
Batch compress · keep 2K/4K · zip in-browser
Web Worker concurrency with no backend server. Built for indie sites and ecommerce product-image batches.
Only resizes if longer than this. Most photos are already smaller — size often barely changes here; use Quality / Exact size instead.
