Enterprise-Grade Security
Your files never leave your device. The encryption happens entirely in your browser, making this the most secure way to handle sensitive legal, financial, or medical documents. Unlike cloud-based encryption services where your unencrypted file must first be uploaded, our approach ensures your document is never exposed in an unencrypted state outside your device.
Protect Before You Share
Before emailing confidential documents, adding password protection is a critical security step. Even if your email is intercepted or accidentally forwarded, the document remains unreadable without the password. This is especially important for financial reports, legal agreements, and any document containing personal information.
How PDF Encryption Works
PDF encryption uses industry-standard algorithms to scramble the document's content. When someone tries to open the file, their PDF reader asks for the password, uses it to derive an encryption key, and decrypts the content on the fly. Without the correct password, the content appears as unreadable binary data — even if someone accesses the raw file.
Frequently Asked Questions
What happens if I forget my password?
Because we process everything locally and don't store your files or passwords, we cannot recover it for you. Please ensure you keep your password safe. We recommend using a password manager to store your PDF passwords securely.
Is the encryption secure?
Yes, we use standard PDF encryption protocols provided by the pdf-lib library to ensure your document remains locked to anyone without the password. The encryption follows the PDF specification standard.
Can I set different passwords for opening and editing?
Our tool sets a user password that is required to open and view the document. This provides the strongest level of protection for your content.
Is my password sent to your servers?
Absolutely not. The password you enter is used exclusively within your browser to encrypt the PDF. It is never transmitted, stored, or visible to anyone but you.
What types of documents should I protect?
Any document containing sensitive information — financial records, legal contracts, medical records, personal identification documents, business proposals, and confidential reports — should be password protected before sharing.
Can the recipient unlock the PDF with the password I set?
Yes. Simply share the password with the intended recipient through a secure channel (in person, phone call, or encrypted message). They can then open the PDF using any standard PDF reader.
