Best for password protection
Use Protect PDF when a contract, invoice, ID document, statement, or private report should require a password before opening.
About Protect PDF
Pagivo PDF applies real AES-256 encryption to your document using Apache PDFBox, the same encryption standard used by banks and government agencies. Once protected, the PDF cannot be opened without the correct password - not by any viewer, browser, or reader. This is the right tool for securing contracts, financial statements, personal identification documents, or any sensitive PDF before sharing it over email or cloud storage. The password is never logged or stored on our servers.
