What does password protection do for a PDF
Adding a password to a PDF restricts who can open, view, or edit the document. Without the correct password, the file remains inaccessible.
This feature helps prevent unauthorized access and accidental data leaks.
Why you should protect PDFs with a password
PDF files often contain sensitive information such as personal data, business details, invoices, or legal documents.
Password protection adds an extra layer of security when sharing files through email, cloud storage, or messaging apps.
Types of PDF passwords
PDFs can have different types of passwords. An open password prevents unauthorized viewing, while a permissions password restricts actions like printing or editing.
Many tools allow users to apply one or both types.
