Why Masking Your Aadhaar Number Matters
Sharing your unmasked Aadhaar number online exposes you to significant risks, including identity theft, financial fraud, and unauthorized access to your personal data. The Unique Identification Authority of India (UIDAI) explicitly recommends sharing a masked Aadhaar—where only the last 4 digits are visible—to prevent misuse.
This tool is designed to protect you during common situations where Aadhaar is requested as an identity proof.
Common Use Cases for Aadhaar Masking
- Loan Applications: Financial institutions frequently ask for identity proof. Masking your Aadhaar protects your credit profile.
- Rental Agreements and Tenant Verification: Landlords and housing societies often request Aadhaar. Mask the first 8 digits to provide proof of identity safely.
- Job Applications: HR departments collect IDs for onboarding. Limit their data exposure by redacting the sensitive initial digits.
- Address Proof Submissions: If a document like a bank statement doubles as an address proof, the Aadhaar mentioned on it should be masked.
- College Admissions: Universities require ID verification. Keep your student identity safe.
How Our Zero-Upload Tool Works
PDF Pro was built with a fundamental privacy-first architecture. Whether you upload a digital PDF with a text layer or a scanned JPG/PNG image, your file never leaves your device.
For images, we utilize Tesseract.js (WASM) to run OCR entirely inside your browser, combined with the HTML Canvas API to detect and highlight 12-digit Aadhaar numbers. You then manually confirm the highlights to redact them. For digital PDFs, we use pdf.js to extract the text layer and precisely overlay black rectangles. Everything happens locally, ensuring maximum privacy.

"I constantly process lease agreements with sensitive SSNs. This tool is a lifesaver because it processes everything locally."
"Other redactors just draw a box that you can copy-paste under. PDF Pro's true rasterization actually destroys the text. Incredible."
