What is PDF Redaction?
PDF redaction is the process of permanently removing sensitive information from a document before sharing it. Unlike highlighting text in black or placing a black rectangle on top of content, true redaction permanently deletes the underlying data so it cannot be recovered by anyone receiving the file.
Common mistakes — like simply drawing a black box over text in a PDF editor — leave the original content intact in the file structure, where it can be revealed by anyone who copies the text or opens the file in a different viewer. Our tool performs genuine redaction, removing the underlying content entirely.
All redaction processing happens in your browser, which means your sensitive documents — court filings, medical records, financial statements — are never transmitted to any external server.
