Protect PDF Online: Lock Your Documents Securely

In a digital world, protecting your sensitive information is crucial. Whether it's a financial report, legal contract, or private notes, the OriginalPDF Password Locker allows you to quickly encrypt and password-protect your PDF files online for free. Prevent unauthorized access, copying, and printing with military-grade encryption.

100% Secure & Private Processing

Your document security is our top priority. Our encryption engine operates entirely on Client-Side Technology. This means your PDF file and your custom password are processed locally within your web browser. Your private data is never uploaded, tracked, or saved on our servers.

VIP Features of Our PDF Locker

• Advanced Flattening Encryption: Our tool uses PDF.js to flatten your document into high-resolution secure layers before applying AES encryption. This provides double security: a password lock and absolute anti-copy protection.
• Master Owner Password Generation: We automatically generate a highly secure, randomized Owner Password behind the scenes. This ensures that no hacker or unauthorized user can bypass your print restrictions.
• Side-by-Side Clean Layout: Experience a modern, clutter-free interface. Upload your file, type the password, and lock it instantly without unnecessary scrolling.
• Custom Security Permissions: You are in full control. Choose whether the person opening the PDF is allowed to Print the document.
• Double Verification: We require you to type the password twice to ensure there are no typos, saving you from accidentally locking yourself out of your own file.
