Encrypt your PDF with AES-256 so only people with the password can open it. Works in every PDF reader.
Your file and password are sent over HTTPS to our server, processed in a temporary file, and deleted as soon as the result is returned. We never keep a copy.
Upload the PDF, type a password twice, and click Protect PDF. You download an encrypted copy that asks for the password every time it is opened, in any PDF reader.
AES-256, the strongest encryption the PDF standard supports. It is the same encryption Adobe Acrobat uses for its "high" security setting, and it works in Acrobat, Chrome, Edge, Firefox, macOS Preview and mobile PDF apps.
No. Encryption runs on our server because browsers cannot apply PDF encryption on their own. The file and password are sent over HTTPS, processed in a temporary file, and deleted as soon as the protected PDF is returned. We never keep a copy and never log your password.
Nobody can recover it, including us, because we do not store it. Save the password in a password manager before you share the protected file.
It is free with no watermark and no sign-up. Files up to 50 MB are supported. Compress larger PDFs first.
Use our free Remove PDF Password tool. Enter the password once and you get an unlocked copy.
