Password Protect PDF adds an open password to your document so only people who know the password can view it — useful for sending tax documents, contracts, medical records, or any file with sensitive information by email. Set your password, choose whether to also restrict printing or copying, and download the protected file. The encryption is applied using standard PDF security, so the protected file works with any PDF reader that asks for a password before opening. Because the process runs in your browser, your original document and the password you choose are never sent to a server.
