Add Password to PDF
Lock your PDF so it asks for a password to open. Your PDF and password never leave your device.
About Add Password to PDF
Add Password to PDF locks a PDF so that it asks for a password before it opens. You can also block printing, copying and editing with an owner password. The text of the PDF stays selectable because the file is encrypted as it is, not converted to pictures.
The password and the PDF never leave your device: encryption is done inside your browser. The file uses standard 128-bit PDF security that opens in Adobe Reader, Chrome, Edge and other common viewers.

Tips
Use at least 8 characters with letters and numbers; the Random Password Generator can make one.
Write the password down: it cannot be recovered if you forget it.
Printing / copying restrictions are only honoured by PDF viewers; the open password is the real protection.
Share the password through a different channel than the PDF.
