Protect PDF — Coming Soon
Real PDF encryption with AES-256 security is currently under development. This tool will be available in a future update with genuine password protection that works in all PDF readers.
✨ Planned Features
💡 Why is this under development?
True PDF encryption requires encrypting every stream and string inside the PDF file using AES or RC4 algorithms. This cannot be reliably done with current browser-based JavaScript libraries. We are building a proper solution that produces genuinely protected PDFs verified to work in Adobe Acrobat, Chrome, Firefox, and Edge.
