Keep Sensitive PDFs Private
Some documents should not be readable by anyone who gets hold of the file β contracts, statements, medical records, HR letters. Adding an open password encrypts the contents so the file is unreadable without it, which matters most when you email it or store it in shared cloud folders. Choose a password you share with the recipient through a separate channel.
The encryption here is applied locally with AES, the same family of cipher used across the security industry. Because the whole process runs on your device, your password is never transmitted and never stored β there is no server that could leak it.
Encrypted on Your Device
A specialised library performs the encryption inside your browser, then hands you the protected file as a download. Neither the original document nor the password is uploaded anywhere.
