Protect a PDF with a password

Choose the PDF, type a password and download the protected version.

Your files are not uploaded to any server.

How to use it

  1. Choose the PDF.
  2. Type the password twice.
  3. Click Protect PDF.
  4. Keep the password somewhere safe: without it the PDF cannot be opened.

How it works

The PDF is encrypted with 256-bit AES, the strongest method the format supports. Any PDF reader will ask for the password to open it: Adobe Acrobat, your browser, the Windows or Mac viewer, or your phone.

The password is not stored anywhere. If you forget it, neither we nor anyone else can recover the content.

When sharing it, use a different channel than the PDF: for example, the file by email and the password by message.

FAQ

What password should I use?

One with at least 10 characters that you do not use anywhere else. A phrase of several words is easy to remember and hard to guess.

Can I remove the password later?

Yes, with Remove password, by typing the current password.

Is my original PDF protected?

No. A protected copy is downloaded. The original stays the same.

Is the PDF uploaded to a server?

No. Encryption runs in your browser.
