ما هو حماية PDF؟

PDFBasic's Protect PDF tool adds password encryption to your documents using industry-standard 256-bit AES encryption. Set an open password (required to view the document) and/or a permissions password (restricts printing, copying, and editing). This ensures only authorized individuals can access or modify your sensitive files.

كيفية استخدام حماية PDF

Upload your PDF, set an open password and/or permissions password, choose which actions to restrict (printing, copying, editing), and click "Protect." Download your encrypted PDF — it will prompt for the password whenever someone tries to open or modify it.

متى يجب استخدام حماية PDF؟

Protect PDFs when sharing confidential business documents, distributing sensitive financial records, sending legal documents electronically, controlling who can print or copy proprietary materials, or meeting compliance requirements for data protection.

الأسئلة الشائعة

What encryption standard is used?
256-bit AES encryption, the same standard used by banks and government agencies.
Can I set different passwords for viewing vs editing?
Yes! Set an "open" password to restrict viewing and a "permissions" password to restrict editing, printing, and copying.
What if I forget the password?
We don't store your passwords. If you forget, you'll need to use our Unlock PDF tool with the original password.
Is 256-bit AES really secure?
Yes. 256-bit AES is the gold standard for encryption. It would take billions of years to crack with current computing technology.
Can protected PDFs be opened on any device?
Yes. Any standard PDF reader (Adobe Acrobat, Chrome, Preview) supports password-protected PDFs.
