Understanding PDF Encryption and Decryption
PDF encryption is the process of adding a layer of security to a PDF file to prevent unauthorized access. This is typically done by setting a password that is required to open and view the document. Decryption is the process of removing this password protection, assuming you have the correct password.
Why is PDF Security Important?
- Confidentiality: Protect sensitive information such as financial reports, legal contracts, personal data, or confidential business plans from prying eyes.
- Access Control: Ensure that only intended recipients can view your document. This is crucial when sharing files over email or cloud storage.
- Data Integrity: While our tool focuses on open passwords, encryption is the first step in a broader security model that can also prevent unauthorized modifications.
After securing your document, you might need to compress the PDF for easier sharing, or merge it with other documents.
Client-Side for Maximum Privacy
This tool operates entirely within your web browser. When you upload a PDF to encrypt or decrypt it, the file is never sent to our servers. The entire cryptographic process happens locally on your computer. This means your documents and your passwords remain completely private and secure.
