Redact PDF Online — Permanently Hide Confidential Information

Use this tool to black out, blur, or pixelate sensitive text, numbers, signatures, or images in a PDF before you share it. Unlike simply drawing a box over text in a PDF viewer, this tool removes the underlying content from the page — so it can't be recovered by copying text, editing the file, or zooming into a blurred region.

Why redact a PDF?

Privacy & security

Your file is processed on a secure server and deleted automatically within minutes. Redaction is permanent — the covered content is removed from the page data, not just hidden underneath a shape.
