Password Protect PDF
Encrypt a PDF with an open password and optional permission restrictions.
Password Protect a PDF Online
The Password Protect PDF tool adds AES-style encryption to any PDF using an open password that recipients must type to view the document.
Choosing a password
Mix upper- and lower-case letters, numbers, and a symbol. Avoid dictionary words and personal information. Once the file is encrypted there is no recovery — store the password somewhere safe.
Permissions explained
- Printing — controls whether recipients can send the PDF to a printer.
- Copying — controls whether text and images can be selected and copied.
- Editing — controls form filling, annotations, and assembly.
Encryption happens in your browser. Neither the file nor the password is transmitted anywhere.
