Protect PDF: Secure Your Documents with AES Encryption

In an age where data breaches are common, securing your sensitive documents is not just an option—it's a necessity. Whether you are sending financial statements, legal contracts, or personal records, our **Protect PDF** tool ensures that only authorized individuals can access your content.

Using advanced 256-bit AES Encryption, we wrap your PDF in a digital vault that is virtually impossible to crack without the correct password. This service is completely free, runs in your browser, and requires no software installation.

Why Password Protect a PDF?

• Confidentiality: Prevent unauthorized eyes from reading sensitive information like bank account numbers, social security numbers, or trade secrets.
• Control: You decide who gets to see the document by sharing the password only with intended recipients.
• Compliance: Many industries (Legal, Medical, Finance) mandate that digital documents shared via email must be encrypted to comply with regulations like GDPR or HIPAA.
• Peace of Mind: Even if your email is intercepted or you accidentally send the file to the wrong person, the content remains safe and unreadable.

1. Upload: Select or drag and drop your PDF file into the secure upload area.
2. Set Password: Enter a strong password in the input field. We recommend a mix of letters, numbers, and symbols for maximum security.
3. Encrypt: Click the "Encrypt PDF" button. Our server will apply the encryption algorithm instantly.
4. Download: Save your newly secured PDF. When you (or anyone else) try to open it, a password prompt will appear.

What is AES 256-Bit Encryption?

AES (Advanced Encryption Standard) is the industry standard for data security used by governments and banks worldwide. "256-bit" refers to the key length, meaning there are 2^256 possible combinations. To put it simply: it would take a supercomputer millions of years to brute-force crack a file protected with our tool.
