About this tool
A password to open the file, an owner password to lift the limits, and a choice of what a reader may do: print, copy text, change the document, add comments. The encryption is AES-256, the only cipher the current PDF standard still recommends, and it is applied here — the file is not sent anywhere to be locked.
Private by design — your files never leave your device. Toolpit has no upload step and no server that can see your document — the work happens in this tab, on your machine, and stops the moment you close it.
