How to password-protect a PDF

Use this before you send a PDF that should not open for just anyone. Keel encrypts it in your browser. The password is never uploaded to our servers.

1. Open Password-protect PDF Add the PDF you want to encrypt.
2. Choose a password Type it twice. You can also set a separate owner password, and choose whether printing or copying text is allowed.
3. Encrypt Download protected.pdf. Opening it later requires the password you just set.
4. Remove a password you still know If you still have the password, the same page can decrypt the file locally. That is not a recovery service.

If the password is lost, nobody at Keel can open the file. Write it down somewhere you control before you delete the unprotected original.
