What the Redact PDF tool does

A black rectangle drawn over a name usually leaves the name in the file, where anyone can copy it out. That is a common and costly mistake when sharing coursework, case studies and evidence.

This tool removes the marked areas for good. Any page that carries a redaction is rebuilt as an image with the boxes painted in and the original page discarded, so the hidden text cannot be recovered.

How to use it in four steps

  1. Open the Redact tool and choose your PDF.
  2. Drag a box over each name, number or detail to remove.
  3. Check the preview of what will be removed.
  4. Press Redact and download the safe copy.

How students use it

  • Anonymise a case study or interview transcript before you include it.
  • Remove your student number and address from evidence you share.
  • Hide patient or client details in a placement reflection.
  • Prepare a document for blind marking or peer review.

Good to know

  • A redacted page becomes an image, so its text can no longer be selected or searched. Pages you do not mark keep their text.
  • Redaction cannot be undone. Keep your original file safe.
  • Check the finished file carefully. Names can appear in headers, footers and image text too.

Redact PDF — your questions

Is this different from drawing a black box?

Yes. A box only covers text. This tool removes it from the page for good.

Can anyone recover the hidden text?

Not from a page this tool has redacted, because the page is rebuilt without it.

Why can I not search the redacted page?

Redacted pages are saved as images. Unmarked pages keep their searchable text.

Is my file uploaded?

No. All of this happens in your browser.
