About Protect PDF

Confidential reports, financial statements, and legal documents deserve more than a 'please don't share' note. Davirix Protect PDF applies industry-standard AES-256 encryption and lets you set granular permissions: allow viewing but block printing, or permit printing but prevent text copying. You can set separate owner and user passwords for different access levels. The encrypted file works in every major PDF reader — Adobe Acrobat, Preview, Chrome, Firefox — with no plugins required.

• Separate owner and user passwords
• Granular permissions: printing, copying, editing, form filling

Frequently Asked Questions

How strong is the encryption?

We use AES-256, the same standard used by banks and government agencies. It's computationally infeasible to crack with current technology.

Can I remove the password later?

Yes. Use our Unlock PDF tool (coming soon) — you'll need the original password to remove protection.

Will the protected PDF work in all readers?

Yes. AES-256 encrypted PDFs are supported by Adobe Acrobat, macOS Preview, Chrome, Firefox, and all modern PDF readers.
