How to Password Protect Sensitive PDF Documents

Adding Passwords to Your PDFs

Sharing financial data, medical records, or legal drafts via email comes with risks. If your email account is compromised, those attachments are vulnerable.

The Solution: File-Level Encryption

By adding a password directly to the PDF, you ensure that even if a hacker steals the file, they cannot open it without the key.

Guide:

  1. Open the Protect PDF tool.
  2. Upload your document.
  3. Enter a strong password (mix of letters and numbers).
  4. Download your locked file.

Note: There is no "forgot password" feature for encrypted PDFs. If you lose the password, the data is gone forever. This is a feature, not a bug!
