How LocalKit is different

Built for people who
actually care about privacy.

Every tool in LocalKit uses browser-native APIs. Your files never leave your machine — not for compression, not for PDF merging, not for anything. There's no server to breach because we don't have one for your data.

Your medical PDF, your tax doc, your passport scan — none of it ever leaves your browser.
Proof it works
