Why Use Protect PDF?
AES-256 Encryption
Your PDF is protected with the same encryption standard used by banks and governments. AES-256 bit encryption is virtually uncrackable with current technology - it would take billions of years to break through brute force.
Granular Permissions
Control exactly what recipients can do. Allow viewing but block printing. Permit printing but prevent text copying. Block all editing. You decide which actions are allowed for each protected document.
Password Strength Guide
The real-time password strength indicator helps you create secure passwords. See immediately whether your password is weak, fair, good, or strong. Build better security habits.
Universal Compatibility
Protected PDFs work in all standard PDF readers - Adobe Acrobat, Preview, Chrome, Firefox, Edge, and mobile apps. Recipients don't need special software, just the password you provide.
Who Uses PDF Protection
Professionals securing sensitive documents
Business Contracts
Protect NDAs, proposals, and contracts before sending to clients. Ensure only authorized parties can access confidential terms.
Legal Documents
Secure legal filings, court documents, and attorney-client communications. Maintain the confidentiality that professional ethics require.
Financial Reports
Lock down financial statements, tax documents, and investment reports. Protect sensitive financial data from unauthorized access.
Medical Records

How It Works
Upload Your PDF
Drag and drop your PDF file or click to browse. The tool accepts any PDF document regardless of size or complexity.
Set Your Password
Create a strong password using the password field. The strength indicator shows password quality in real-time. Confirm the password to prevent typos.
Configure Permissions
Choose what actions to allow: printing, copying text, or editing. Toggle each permission on or off based on your security needs. Each option explains exactly what it controls.
Download Protected PDF
Click Protect PDF to encrypt your document. Download the secured file and share it. Recipients will need the password to open it.
Tips for PDF Protection
Create Strong Passwords
Use 12+ characters with uppercase, lowercase, numbers, and symbols. The strength indicator helps you build secure passwords. Avoid dictionary words and personal information.
Share Password Separately
Never include the password in the same email as the protected PDF. Use a phone call, text message, or separate communication channel to share passwords securely.
Keep Backups
Always keep an unprotected copy of your original in a secure location. If you forget the password, there's no recovery method - the encryption is that strong.
Choose Permissions Wisely
Think about what recipients actually need to do. For contracts, allow printing but block editing. For drafts, consider blocking everything except viewing.
