PDF security and standards play a critical role in ensuring the integrity, confidentiality, and accessibility of digital documents. With PDFs widely used for business, legal, and government purposes, maintaining compliance with security protocols and industry standards is essential. Modern PDF components provide robust protection mechanisms, allowing organizations to safeguard sensitive information while ensuring documents meet regulatory requirements such as ISO 32000, PDF/A for archiving, and PDF/UA for accessibility. These features help prevent unauthorized access, support legal validity, and enable secure document exchange across different platforms.

Common features include:

PDF Password Protection restricts access to a document using user and owner passwords for viewing and editing controls.
Encrypting/Decrypting PDFs ensures security with encryption algorithms like AES (Advanced Encryption Standard) to protect files from unauthorized modification.
PDF Redaction permanently removes confidential information, making it unreadable and unrecoverable.
Handwritten Signature support enables users to add freeform ink-based signatures for a more natural signing experience.
PDF Signing ensures document authenticity through digital signatures, allowing verification of origin and integrity.
PDF Standards Conformance guarantees compliance by validating documents against standards like PDF/A for long-term archiving or PDF/UA for accessibility.
Accessibility includes features such as tagging, text-to-speech support, and structured navigation, ensuring content is usable by individuals with disabilities.
