How to Redact a PDF: Protecting Your Sensitive Information

Redaction is more than just drawing a black box over text. If done incorrectly, the original data might still be present in the underlying metadata or text layer. In this guide, we'll show you how to professionally redact a PDF so that the information is gone for good, using the advanced tools available at lana-pdf.com.

If you want the dedicated workflow directly, go to Redact PDF Online. If the document is a scan first, run OCR PDF before redacting so the file is easier to review.

Why Proper Redaction Matters

Every year, documents get leaked because someone used a highlighter instead of a true redaction tool, or just drew a box over the text and assumed it was safe. Proper redaction means the covered information does not come along in the file you share.
