Password-Protect or Redact a PDF on Mac

Ensuring the privacy of your PDF files is crucial, and implementing encryption, password protection, or redaction is essential. Mac users can now enhance the security of their PDFs by utilizing password protection or redaction features within the UPDF program. Alternatively, users can choose to watch the video guide below for a demonstration on how to implement these security measures effectively.

Add an Open Password

UPDF provides extra security to your PDF documents by applying an open password. The purpose of an open password is to restrict your document from an unauthorized person to open and view it.

  • To add an open password to your PDF, open your PDF in UPDF first.
  • Click the "Protect Using Password" icon.

Add a Permissions Password

Permission Password is also known as Master Password. A permission password allows you to restrict printing, editing, and copying content in the PDF.

  • Choose the "Permissions" option in the "Encrypt with Password" window.

Redact PDF

Besides restricting access by the implication of the passwords, you can also limit text revelation via the PDF text redaction feature. It lets you black out the selected portion of the PDF content. Once redacted, no one can view the content; thus, your data privacy will remain intact.

Hop on below to learn how you can redact PDFs with UPDF!

  • Open the desired PDF in UPDF.
  • Go to the Redact mode and choose any of the following options depending on your convenience:

Mark for Redaction – Click on this option, select the text you want to redact, and click the Apply button in the top right corner.

Redact Pages – Owing to this option, you can select whether you want to redact the current page, all of the PDF pages at once, or a custom range of pages. You can also choose to redact odd or even pages. Just select the range and hit OK to apply redaction.
