About this tool

What Redact PDF does

Redact PDF is a free, web-based tool that permanently removes sensitive content from PDF documents. Users upload a file, select specific areas of text or images to black out, and download a modified version where the chosen material is excised from the underlying code rather than merely hidden. The service is designed for professionals and individuals who need to protect privacy and ensure compliance with data protection regulations when sharing confidential records, legal documents, or corporate reports. The result is a cleaned PDF in which the redacted sections are truly deleted and cannot be recovered.
