Redact PDF

Permanently black out sensitive names, account numbers, and images before sharing a PDF. Redactions are baked into the exported file — not just covered visually.

Open Redact PDF

Editing, annotation, signing, and redaction are different

Edit PDF is for adding visible text, images, and shapes. Annotate PDF is better for review marks and comments. Sign PDF places your own signature on a document; it does not create an identity-verification service. Redact PDF permanently removes marked information from the exported copy, which is safer than drawing a black rectangle over sensitive text.

Review the exported copy

  • Confirm additions appear on the intended page
  • Zoom in to check signature and watermark placement
  • Test that redacted information cannot be selected or copied
