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.

FAQ

Can I convert many images at once?
Yes. Drop a batch, compress with multi-core Web Workers, then pack locally—usually much faster than upload → queue → download on cloud tools.
What about transparent PNGs?
WebP output usually keeps transparency. If a target platform doesn’t support WebP, switch back to PNG or JPEG.
Is this a cloud converter?
No. Nothing hits a backend server. Files never leave your device.
