Processed on our server, then deleted
Unlike merge, split and reorder, this tool needs our server. The file travels over an encrypted connection, is used only for this operation and is deleted within 60 minutes, or right away with the button you see after the download. It is never shared with anyone.
How to use
- Choose protect or unlock.
- Select a PDF and enter the password.
- Download the result.
