About

LeanPix compresses images entirely inside your browser. Your files are never uploaded, stored, or seen by us.

Why in-browser?

Uploading means waiting, size caps, and trusting a third party. Modern browsers encode JPEG, WebP, and AVIF locally at excellent quality, so we run that work in Web Workers and keep the interface responsive across large batches.

How quality is chosen

Auto mode balances size against quality based on format and file size. Large photos take stronger compression without visible loss; small ones are treated conservatively. Set quality manually from 1 to 100 whenever you want full control.
