Protect PDF

Set up a solid security firewall for your documents

In the process of exchanging work via the Internet, you often have to email personnel salary statements, confidential price bids, economic sales contracts or internal financial documents. If you just send a regular PDF file, anyone who forwards the wrong email or gets the link can open it and see all of your business's sensitive data.

iTools' PDF Password Lock tool helps you encrypt files using the international standard AES algorithm, ensuring that only those with the password you provide can open and view the content.

Advanced levels of document protection

• AES 128-bit & 256-bit encryption standard: Extremely secure encryption standard, cannot be cracked by normal password cracking software.
• Required to enter a password when opening a file (User Password): When opening a file on any device (phone, tablet or laptop), a dialog box will appear asking for password protection.
• Detailed access permissions (Owner Permissions): Allows you to set viewer permissions: allow reading but prevent printing to paper or prevent text from being copied out.
• Security right in the browser: The encryption process takes place locally, the password you set is never transmitted to the server, absolutely 100%.

Frequently Asked Questions (FAQ)

1. If I forget my password, can I get it back?

Because the application system standardizes high-level encryption and does not save your password on the server, you are required to remember the password. Please save the password in a safe place before clicking to lock the file.

2. Does the recipient need to install any additional software to open the locked file?

No. Chrome, Edge, Safari browsers or the default file reader software on the phone all support a standard password input dialog box for the recipient to type in the code to see immediately.
