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.
Fixed for this converter. Homepage can switch formats.
Tip: Max edge keeps 2K/4K fidelity—it won't shrink small images. To force a smaller file, lower Quality or switch to Exact size.
