Legal PDF redactor — find sensitive data locally

Nothing uploadedTested up to 256 MB

Scan a PDF locally for common sensitive identifiers and custom patterns, review every match, then permanently redact approved regions without uploading the document.

Review a legal-production PDF for common sensitive identifiers before disclosure. The browser-local scanner can find Social Security numbers, EINs, U.S. phone numbers, email addresses, payment-card numbers that pass a Luhn check, dates of birth, and custom regular expressions. Every proposed rectangle stays editable before the existing destructive redaction engine rebuilds affected pages and performs its privacy verification checks. Pattern matching only examines extractable PDF text: scanned pages, unusual text encoding, fragmented text runs, names, addresses, privilege content, and context-specific confidential information can require manual review. The PDF is processed locally in your browser and is not uploaded to a document-processing server, up to 256 MB.

Raster output

150 DPI is the default. Higher values improve small text but increase processing time and file size.

Review a legal-production PDF for sensitive identifiers before disclosure

  1. 1

    Choose the production PDF and let the browser render local previews.

  2. 2

    Enable the sensitive-data patterns that apply to the matter and add any matter-specific regular expressions.

  3. 3

    Scan the extractable text, then inspect every proposed redaction rectangle.

  4. 4

    Adjust, add, or remove regions manually and choose hidden-data cleanup options.

  5. 5

    Create the rebuilt PDF, review the verification report, and perform your normal production QA before disclosure.

Does automatic pattern detection guarantee that a legal production is fully redacted?

No. The scanner only matches configured patterns in extractable PDF text. Scans without a text layer, fragmented or unusually encoded text, names, addresses, privileged material, and context-specific confidential information can be missed. Treat detection as a review aid and perform the legal and production QA required for your matter.
