Protect PDF

A tool to protect PDF files lets you set granular permission controls that determine what users can do with the document. Beyond password protection, PDF security includes restrictions on printing, editing, copying text, form filling, and other actions. These permissions work alongside or independently from open passwords.

Content creators and publishers distribute PDFs with printing disabled to prevent unauthorized reproduction. Editing is restricted to maintain the integrity of the document content. Text copying can be limited to protect intellectual property.

Educational institutions distribute exam papers with permissions that prevent printing and copying. This ensures the exam content remains confidential and is not reproduced or shared by students. Only authorized personnel can modify the document.

The permission password is separate from the document open password. You can set a document that anyone can open with no password, but only users with the permission password can print or edit. This provides flexibility in how restrictions are applied.

Each permission type has an independent control. You can allow printing but restrict editing. You can allow form filling but restrict text copying. This granularity lets you tailor restrictions to your specific needs.

Corporate document control systems use permission restrictions to enforce document handling policies. Confidential reports can be configured so recipients can view but cannot print, copy, or modify the content. Using this tool you can secure PDF file access according to your policy.

Permission restrictions are embedded in the PDF and respected by most PDF readers including Adobe Acrobat and Foxit. While advanced users may be able to bypass simple restrictions, they provide a useful layer of document control for most distribution scenarios.

Combined with password encryption, permission restrictions provide comprehensive document security. The open password controls who can view the file, while permission restrictions control what authorized viewers can do with it.
