How this works
This tool encrypts your PDF with the password you choose, entirely in your browser. The encrypted file requires that password to be opened in any PDF reader — Adobe Acrobat, browser PDF viewers, Preview, and others.
Frequently asked questions
Can I recover the password if I forget it?
No. The password isn't stored anywhere by this tool or sent to any server, so there's no way to recover a forgotten password. Keep a copy somewhere safe, like a password manager.
Is my file uploaded anywhere?
No. Encryption happens locally in your browser. Neither your file nor your password ever leaves your device.
Can I remove a password from a PDF I already protected?
An unlock tool for removing existing passwords is on our roadmap. For now, this tool covers adding a new password.
