01What is Aadhaar Masking Tool?
The ToolWala AI Aadhaar Masking Tool automatically detects and redacts the first 8 digits of your Aadhaar number, leaving only the last 4 digits visible as per UIDAI privacy guidelines (e.g. XXXX XXXX 1234). Operating entirely client-side, the tool uses high-accuracy local OCR to scan your document layout and cover sensitive numbers. It also supports manual masking, custom blurs for QR codes or photos, watermarks, and multi-format exports (PDF, PNG, JPG)—ensuring absolute privacy for bank updates, SIM registrations, and rental agreements.

Upload your Aadhaar card image (JPG, PNG, WEBP) or drop a scanned PDF file directly into the workspace.
The local OCR engine will automatically run a secure scan to locate your Aadhaar number, overlaying a masking box.
Fine-tune the results by adding custom manual redaction or blur zones to hide other sensitive fields like QR codes or portrait photos.
Toggle the watermark option to overlay a secure, transparent 'SECURE MASKED COPY' text for safety.
