What is PDF Redactor?
PDF Redactor is a free online tool that permanently removes sensitive content from PDF documents.
Upload a PDF, draw black rectangles over the text and images you want to hide, and download a redacted copy. Unlike simple highlighting or overlays, redaction draws solid black rectangles directly on the page content and flattens the form layer — the covered content is destroyed and cannot be recovered. Ideal for removing personal information, confidential data, or sensitive details before sharing documents.
