BooPDF encrypts your PDF with industry-standard AES-256 — the same algorithm used by banks. Set an open password and optional permissions.
Password protection is useful when you need to send contracts, payroll files, invoices, statements, or internal documents to a known recipient. It helps prevent casual access if a file is forwarded or stored in the wrong place.
The open password controls whether someone can read the file. Printing and copying permissions are flags that many PDF readers respect, but they are not a substitute for choosing a strong password and sharing it carefully.
No. We use it to encrypt your file in memory then discard it.
