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.

Frequently Asked Questions

What does redacting a PDF do?

Redaction permanently removes visible text, images, or areas from a PDF by covering them with black bars — unlike simply drawing a box, redaction actually removes the underlying content so it cannot be recovered.

Is redaction truly permanent?

Yes. Proper PDF redaction removes underlying content from the PDF stream — not just covering it visually. After redaction, the hidden content is permanently unrecoverable from the output file.

Can I redact specific words or phrases automatically?

Yes. Use the search-and-redact feature to find all instances of a word, phrase, or pattern (like credit card numbers or SSNs) and redact them across every page with one click.

Does redaction run locally in the browser?

Yes. All redaction processing happens client-side via WebAssembly. Your sensitive document never reaches any server.

Can I undo a redaction?

No. Redaction is permanent and irreversible. Always save a backup copy of the original PDF before applying redactions.
