Password Protect PDF — Secure & Encrypt
Lock your confidential PDFs with a strong password before sharing. AES-256 encryption ensures nobody can open it without your key.
Sending a PDF with sensitive business data, personal identification, or financial records over email or messaging apps without a password is high risk. GenZDoc adds AES-256 bit encryption to your PDF — the same standard used by banks — directly in your browser. Set a strong open password, and optionally restrict printing, editing, or copying with separate permission settings.

Frequently Asked Questions
What encryption standard is used?
AES-256 bit encryption, which is the same standard used by major banks and government agencies worldwide.
Can the recipient open it on any PDF viewer?
Yes. Password-protected PDFs created by GenZDoc are compatible with Adobe Acrobat, Mac Preview, Foxit, and all other standard PDF viewers.
Is there a way to restrict printing or copying separately?
Yes. Beyond the open password, you can also set permission restrictions that prevent printing, copying text, or editing the document independently.
What if I forget the password I set?
There is no way to recover it — that is what makes it secure. Write your password down in a safe place before adding encryption.
