PDF Redactor (PII Sanitizer)
The NexVaani PDF Redactor provides legal, financial, and healthcare professionals with an in-browser utility to permanently black out and sanitize sensitive Personally Identifiable Information (PII) before documents are shared publicly or transmitted over email. Draw black redaction rectangles over Social Security Numbers (SSN), Indian PAN numbers, bank routing numbers, addresses, and physical signatures. Using client-side pdf-lib rendering, the tool permanently stamps solid blackout vectors into the PDF object stream, ensuring redacted data cannot be highlighted, copied, or recovered.
The NexVaani PDF Redactor permanently removes sensitive PII and confidential numbers from PDF documents by burning blackout vectors into the file locally inside your browser.
