Secure your PDF documents.
ExpertPDF Pdf Security is a .NET library that enables applications to apply encryption and permission settings to PDF documents. Developers can define passwords, restrict document actions such as printing or copying, and configure protection rules directly in code when generating secure PDF files within applications.

PDF Encryption Support

Applies encryption to PDF documents to protect content from unauthorized access. Applications can configure encryption settings programmatically when generating documents.

User and Owner Password Protection

Supports defining both user and owner passwords for PDF documents. A user password controls who can open the document, while an owner password governs permission settings such as printing, copying, and editing.

Configurable Document Permissions

Allows applications to define restrictions on how recipients interact with PDF documents. Developers can control actions such as printing, copying text or graphics, editing content, or adding annotations.

Protection for Generated PDF Files

Works with applications that generate PDF documents dynamically, such as reporting systems, invoicing platforms, or document publishing solutions. Security settings can be applied during document creation to ensure files are protected before distribution.

Control Printing and Content Extraction

Provides permission settings that determine whether users can print documents or extract text and graphics.

Programmatic Security Configuration

Enables developers to configure encryption and permission settings through application code. This approach supports dynamic security policies where protection rules can vary depending on document type.

Consistent Document Security Policies

Allows applications to apply consistent security configurations across multiple generated documents. By defining security parameters within the application, developers can ensure that protected PDF files follow the same access and permission rules.

Secure Distribution of Sensitive Documents

Helps protect documents that contain confidential or regulated information. Encryption and permission restrictions ensure that PDF files distributed to users maintain controlled access and limited functionality according to defined policies.
