How to Redact a PDF (Permanently Remove Sensitive Info)
Redact PDFfiles to permanently remove sensitive information before sharing them. PDF redaction can help hide personal details, confidential text, account information, and other content that should not be visible.
What separates real redaction from fake redaction
Adding a black rectangle as an overlay layer — what some PDF tools do — leaves the original text underneath. Anyone with Acrobat can disable layers and reveal the supposedly-redacted content. Real redaction draws into the actual page content stream, with the rectangle becoming part of the page itself. PDFPuddle uses the second approach via pdf-lib's drawRectangle.
How to redact in PDFPuddle
Open Redact PDF, upload your document, specify pages to redact (or 'all'), and choose the area: full page, top half, or bottom half. Click Redact Pages — the affected areas are permanently obscured by opaque black rectangles.
When you need word-level redaction
PDFPuddle redacts by page area. For surgical word- or sentence-level redaction (covering one specific name in the middle of a paragraph), Adobe Acrobat's redaction tools handle that case. PDFPuddle covers the most common bulk redaction needs.
Redaction for compliance
GDPR and similar laws mandate that personal data shared in a non-business context should be redacted before sharing. Maintain an audit trail: keep the original alongside the redacted version, with a record of who redacted what and when. PDFPuddle handles the redaction step; the audit trail is your responsibility.
