Redact PDF
True redaction: mark areas visually or search for terms across all pages, then affected pages are rebuilt from rendered images with black vector overlays - the underlying text is gone, not hidden. Every export is verified against extractable text so you know the redaction held.

Processed locally in your browser. True redaction: pages you mark are rebuilt from a rendered image with the content permanently removed — not just covered. Text on those pages becomes non-selectable. Keep your original file; this cannot be undone. Redacting a signed PDF normally invalidates its existing cryptographic signatures.

Frequently asked questions
▸Why is this different from whiteout or a black rectangle?
Covering leaves the text intact underneath where anyone with tools can copy it. Redaction rebuilds the page itself so the data physically no longer exists.
▸Why does redacted page text become non-selectable?
Secure removal requires replacing the page with its rendered image. This is the honest trade-off; we verify removal rather than pretend otherwise.
