Add password protection and encryption to your PDF documents. Restrict printing, copying, and editing permissions. Secure sensitive documents with strong AES encryption without installing any software.
The open password is required to view the document. The permission password controls what actions (print, copy, edit) are allowed.
We use AES 256-bit encryption, the same standard used by banks and government agencies.
You can process files one at a time. Each file can have its own unique password and permission settings.
