PDF Password Protector

This tool provides comprehensive PDF security with two password types: User Password (to open) and Owner Password (to modify). Features include 128-bit or 256-bit AES encryption, granular permissions control (print, copy, modify, annotate), and metadata protection. You can set different passwords for viewing and editing, ensuring complete document control.

Simply upload your PDF, enter a strong password for opening the document, and optionally set an owner password for edit permissions. Choose your encryption strength (256-bit recommended) and select which actions to allow or restrict. Click "Protect PDF" and download your secured file. The tool shows password strength indicators to help you create secure passwords.

Yes, password-protected PDFs created with this tool work with all standard PDF readers including Adobe Acrobat, Chrome, Firefox, Edge, and mobile PDF apps. The encryption standards used (AES-128/256) are industry-standard and universally supported. Recipients only need the password to open - no special software required.

The tool uses military-grade AES encryption (128-bit or 256-bit) which is virtually unbreakable with current technology. All encryption happens locally in your browser - your file and passwords never leave your device. For maximum security, use strong passwords with mixed characters, and never share passwords through insecure channels.

Yes! Use the two-password system: set a User Password for people who should only view the document, and an Owner Password for those who need full control. You can restrict specific actions like printing, copying text, or modifying the document. Anyone with the owner password bypasses all restrictions, while user password holders respect the set permissions.
