How to password protect a PDF

Below we show how to encrypt a PDF file with a password and how to apply PDF restrictions.

  1. Upload your files

    Files are safely uploaded over an encrypted connection. Files stay secure. After processing, they are permanently deleted.

    Rather not upload your files and work with them offline?
    Try Sejda Desktop. Same features as the online service, and the files never leave your computer.

    Click 'Upload' and select files from your local computer.

    Dragging and dropping files to the page also works.

    Dropbox or Google Drive files

    You can pick PDF files from Dropbox or Google Drive too.

    Expand the 'Upload' dropdown and select your files.

  2. Choose a strong password

    When opening the document, users will be asked to provide this password. Make sure it's a strong password, recommended 16 characters or more.

    Optionally, choose an owner password as well

    This is the password that users will be asked when attempting to make changes to the document, after the document is already opened.

  3. Select optional PDF restrictions

    Choose what PDF features should be allowed. For example printing can be restricted, or filling forms and commenting can be disabled

    Depending on the software used for opening the PDF file, these permissions may or may not be enforced.

  4. Save your changes

    Click Encrypt PDF and then Download your protected PDF.
