What information can Smart Redaction detect?

It can detect emails, phone numbers, Social Security numbers, credit card numbers, addresses, names, and other PII (Personally Identifiable Information).

Is the redaction permanent?

Yes! Unlike simple black boxes, our redaction permanently removes the text content from the PDF. The original text cannot be recovered.

Does my PDF leave my device?

No. All redaction processing happens locally in your browser. Your sensitive documents are never uploaded to any server.

Can I manually select what to redact?

Yes! You can review AI suggestions and add or remove redactions before applying them. Full control is in your hands.

SafeShare Standard

Local processing

Clean image-only rebuild

Fail-closed verification

The export is created only from reviewed page images. Original text layers, attachments, scripts, forms, comments, hidden layers, and metadata are not copied.

Image-only output is less searchable and accessible. Automated detection can miss sensitive information; review every page.

Manual redaction

Turn this on to draw redaction boxes directly on any page.

Find exact text

Use Find, Detect sensitive data, or turn on Manual redact to mark areas.

Upload a PDF to review pages and mark redaction areas.

How It Works

Step 1: Upload Your PDF

Drop your PDF into the browser. The file stays on your device — nothing is uploaded to any server.

Step 2: Find Candidate Data

Local OCR and bounded patterns look for emails, US phone numbers, SSNs, and card-like numbers. Exact-text search and manual marking cover additional cases.

Step 3: Review, Rebuild & Verify

Review every page, then build a new image-only PDF. SafeShare reopens the export, inventories prohibited PDF objects, checks redaction pixels, and rescans approved terms before enabling download.

Why Use This Tool

Clean image-only rebuild instead of a recoverable black-box overlay
Independent final-output checks fail closed when verification is incomplete
Local processing — document bytes and detected values stay on your device
Content-free Verification Report with hashes, counts, and check results

Common Use Cases

Prepare a reviewed copy before sharing legal, HR, financial, client, or AI-bound documents. Local processing can reduce third-party data transfer, but automated detection may miss sensitive information and does not certify GDPR, HIPAA, de-identification, privilege, or legal compliance. Human review remains required.
