🔒 Your privacy, by design
This app is built so your documents never leave your device. Here's exactly how:
Everything runs in your browser. PDFs and images are opened with the browser's File API and processed on your device — merging, editing, encrypting, form-filling, text extraction — all locally.
Nothing is uploaded. There is no server, no backend, and no upload endpoint. No network request ever carries your files.
Held in memory only. Files live in this tab's memory for your session. Closing the tab, reloading, or clicking Clear all discards them immediately.
Ads & cookies. The PDF tools set no cookies. To keep LambiPdf free we may show ads (Google AdSense); only with your consent can our ad partner set cookies. You can decline, and change your choice anytime via “Cookie settings” in the footer. The app itself uses no analytics.
Passwords stay local. A password you type to open a protected PDF is used only in your browser and is never stored or sent.
Only what you export is saved. Exported files land in your Downloads folder because you asked — that's the only thing written to disk.
