How to Password-Protect a PDF Before Sending It
Encrypt a PDF with a password and set print/copy permissions — processed in your browser so even we never see your password.
Payslips, ID scans, contract drafts — email is not a safe place for them in plain form. Adding real encryption takes a minute, and if you do it with a client-side tool, the unprotected file and the password never leave your device at all.
Protect in 3 steps
- Open the Protect PDF tool with your file.
- Set an open password (this encrypts the file), and optionally restrict printing, copying, or editing.
- Download the encrypted file and send it — share the password by a different channel, like a phone call or chat message.
Choosing a password that holds up
- Length beats cleverness: a 12+ character phrase is far stronger than a short "complex" string.
- Never put the password in the same email as the file — that defeats the whole point.
- Agree on a convention with regular contacts (for example, a shared code word plus the date) so you do not have to transmit passwords at all.

Need to open your own protected statements without typing the password every time? Unlock PDF removes the password from files you can already open. Want to hide only certain parts of a document instead of locking all of it? Use Redact to permanently black out the sensitive lines before sharing.
Frequently asked questions
How strong is the encryption?
Standard PDF AES encryption, applied locally in your browser. Without the password, the content is unreadable.
What if the recipient forgets the password?
There is no recovery — that is what makes it secure. Keep the original unprotected file safely on your own device and re-send if needed.
Can I stop the recipient from printing or copying?
Yes, permission flags let you restrict printing, copying, and editing. Note that permission flags depend on the reader app honoring them — the open password is the hard protection.
