PDF protection and permissions

Pdf documents can have several permissions but if not encrypted, these settings can be circumvented by different kinds of software. Unencrypted PDFs implicitly have all permissions allowed.

Permissions

• accessibility: Can users use screen readers and accessibility tools to read the PDF?
• Extract: Can users extract contents?
• Annotation: Can users modify annotations?
• Assembly: Can users arrange document contents?
• Form: Can users fill out forms?
• Other: Can users modify the document?
• Print low resolution: Can users print the document at low resolution?
• Print high resolution: Can users print the document at high resolution?
