Smart Document & PII Redactor — Auto-detect & blackout SSN, credit cards, emails, and phones 100% locally
Protect confidential documents, bank statements, and IDs before sharing. Client-side scanning with 1-click blackouts and custom box drawing.
Step-by-Step Client-Side Workflow
- 1. Local Document Rendering: Your document is converted into rasterized pixels strictly inside your browser memory using the HTML5 Canvas API without any network upload.
- 2. Optical & Pattern Recognition: Local heuristic regex and edge detectors scan for sensitive identifiers like Social Security Numbers, credit card digits, and email addresses.
- 3. Permanent Pixel Destruction: When you apply redactions, black pixels permanently overwrite the sensitive regions. Unlike basic PDF highlights, redacted text cannot be copied or reversed.
Why Use VaultTools Zero-Upload Architecture
- GDPR & HIPAA Compliant: Because no Protected Health Information (PHI) or personal data transmits over the wire, compliance risk is reduced to zero.
- Zero File Size Caps: Process multi-megabyte contracts instantly without queuing or server connection timeouts.
- Permanent Burn-in: Redaction rectangles are rasterized into the image bitmap, ensuring metadata or underlying vector text cannot be recovered.
Frequently Asked Questions
Can someone undo or remove the black boxes to see my private data?
No. VaultTools permanently burns the black boxes directly into the image canvas pixels before saving. The underlying text is completely replaced with solid color and cannot be unmasked or highlighted.
Does VaultTools save a copy of my bank statement on its server?
Never. VaultTools is a zero-knowledge static web application. It has no backend server or cloud database. Your files exist only in your computer RAM and vanish the second you close the tab.
Can I redact custom areas like handwritten signatures or company stamps?
Yes! Click and drag your mouse anywhere across the document preview to draw custom blackout rectangles over signatures, logos, or addresses.
