About Redact PDF
Sharing documents often means hiding sensitive details, and a simple black box is not enough — the text underneath can still be extracted. ILikePdf Redact PDF permanently removes the underlying content when you cover it, so nothing hidden survives in the file. You can draw redaction boxes manually or auto-redact every occurrence of a searched term across the document. The redacted copy is generated locally, keeping both the original and the output private.
