Free online PDF redaction

Remove sensitive information for good

Drawing a black rectangle in a normal editor often leaves the text underneath — anyone can copy it out. iHeartPDF Redact PDF removes it for real.

Search for names, account numbers or e-mail addresses to mark every occurrence at once, or drag boxes over any area. Pages with redactions are flattened, so the hidden text can’t be selected, copied or recovered.
