RedactNinja

Redact PDFs and convert MSG, PST or Purview ZIP evidence into local PDFs with progress tracking.

RedactNinja helps reviewers redact searchable PDFs without uploading the document to a server. Choose a PDF from your device, select built in UK PII detection rules, add names or keywords, add do not redact terms, and download a redacted PDF. RedactNinja can also clean basic PDF metadata, run a visible redaction safety check and create a downloadable redaction receipt. The extension is designed for quick one document redaction. For full subject access request workflows, including case setup, review tracking, mailbox handling and disclosure packs, use the full RedactNinja app at https://app.redactninja.com/ Privacy is the main design rule. RedactNinja does not request host permissions, does not inject content into websites, does not read your tabs, does not use analytics and does not upload selected PDFs. Processing happens locally in the extension page. A human reviewer should always check the output before disclosure.
