AES-256 Encryption
We use industry-standard encryption to ensure your PDF stays private and secure from unauthorized access.
No Server Uploads
Your files never leave your device. All encryption happens locally in your browser for 100% privacy.
Quality Preserved
Protecting your PDF doesn't change its content or quality. Your document remains exactly as it was, just secured.
Professional PDF Security Made Simple
Keep your confidential documents safe from prying eyes with our advanced encryption tool.
Why Password Protect Your PDFs?
In an era of digital data breaches, securing your information is more important than ever. Password protecting your PDFs ensures that even if a file is shared or intercepted, its contents remain unreadable to anyone without the correct credentials. It's the standard for professional document sharing.
Advanced Browser-Based Encryption
We believe privacy shouldn't be complicated. Our tool uses WebAssembly and PDF-lib to perform complex encryption routines directly in your browser. Unlike other online converters that store your files, we never even see your documents or your passwords.
Compatible with All PDF Viewers
The protection we apply follows standard PDF specifications. This means your password-protected PDF will work perfectly across all devices and software, including Adobe Acrobat, Chrome, macOS Preview, and mobile PDF readers.
The Ultimate Way to Secure Your PDF Documents
BosConvertPro's Protect PDF tool offers professional-grade security for your sensitive documents. Whether it's financial records, legal contracts, or personal IDs, our tool ensures that only those with the password can access the content. By utilizing modern web technologies, we've brought military-grade encryption directly to your browser, ensuring your data remains entirely under your control at all times.
