Password-protect a PDF — without uploading it
Set a password to open the PDF and choose whether people can print, copy or edit it.
Encryption happens in your browser with 256-bit AES: the file and the password stay on your computer.
How to add a password to a PDF
Open the PDF, type the password twice and download the protected copy. Anyone who receives it must enter the password to open it, in any PDF reader.
The protection uses 256-bit AES, the strongest option in the PDF standard. Before handing you the file, the tool checks that it opens with the password you chose.
Block printing, copying and editing
Untick what you want to block: printing, copying text and images, or editing and filling in forms. Most PDF readers honor these restrictions. Keep the password safe — without it, nobody can open the file, not even RoseLab.
