How to use Redact PDF
- Choose or drop your PDF.
- Type the text to remove.
- Select Redact PDF, then check the result before sharing.
Why a black box is not enough
Drawing a black rectangle over text in most PDF editors only hides it — the words are still in the file and can be copied or searched. This tool finds every match, draws a black bar over it, and then converts each affected page into an image at the resolution you choose. The original text on those pages no longer exists in the file.
Pages without a match are left untouched. Because redacted pages become images, their other text is no longer selectable either; run OCR PDF afterwards if you need it searchable again.
Before you share
Always open the redacted file and check every page. Matching is by text, so it cannot find words that are part of an image or a scan — for scanned documents, run OCR PDF first. Advanced users can match patterns with regular expressions under More options.
