About Protect PDF Tool
Securing sensitive documents before sharing them is crucial. Our free online Protect PDF tool allows you to encrypt your PDF files with a strong password, preventing unauthorized users from opening, reading, or printing the contents.
How It Works
The tool uses a local JavaScript library to apply AES encryption to your PDF document. You provide a password, and the tool rewrites the PDF file, locking the contents so that they can only be decrypted and viewed by someone who knows the password.
Common Use Cases
- Securing financial statements or tax documents before emailing them
- Protecting confidential HR records or employee contracts
- Ensuring privacy for personal medical records or legal documents
- Adding an extra layer of security to files stored in the cloud
