Redact PDF Free | PaperStack

⚠️ How this works — please read before you rely on this:

Any page you redact is converted into a flattened image. This guarantees the covered content can't be recovered, copied, or selected — but that page will no longer be searchable or text-selectable.
Pages you don't touch stay exactly as they were (still text/searchable).
Make sure your black box fully covers the sensitive area — zoom in if needed. Redaction only removes what's inside the box you draw.
Always open the downloaded PDF and double-check before sharing it.
