Password

Checked against the file on your own device. It is never sent anywhere, and we cannot open a file without it.

Your file never leaves this device. Processing happens in your browser, so nothing is uploaded and nothing is stored.

Adding a password

Locking a PDF lives in Protect PDF, on the tab next to this one — so you can add a password to one file and take it off another without changing pages.
