Professional-Grade Local Redaction
Unlike basic editors that just hide text behind a black box, OncePDF's Smart Redaction tool actually destroys the underlying data. When you redact a name or a number, the text characters are physically removed from the PDF structure, ensuring they can never be recovered through copy-pasting or search.
