Why LokalPDF?
Privacy
A contract, an ID scan, a medical report — whatever you process stays on your disk. We never receive it.
Speed
No 50 MB upload and no queue. Processing starts the moment you pick your files.
No limits
No account, no daily quota, no watermark. Completely free.
Works offline
Install LokalPDF as an app and the tools work without a connection — proof that nothing travels to a server.
Verifiable
A counter on every tool shows how many bytes were sent to a server: 0 B. The code is open source under the MIT license.
Tools chain together
Merge, then compress, then sign — the result moves to the next tool without downloading and re-selecting.
