Common Questions

Aadhaar masking replaces the first 8 digits of your 12-digit Aadhaar number with cross marks (e.g., XXXX XXXX 1234). This obscures your unique identifier while keeping the last 4 digits visible for verification, preventing misuse.
Yes, our Aadhaar Masking Tool runs entirely client-side. The OCR engine and image modifications occur strictly within your web browser sandbox. No file data, texts, or metadata are ever transmitted to our servers.
No. All scanning, character detection, and image manipulation are completed locally inside your browser cache. The tool can be run completely offline after loading the initial page layout.
Yes! Our engine rendering pipeline supports scanned PDF cards, rendering page views into clean images so you can apply auto or manual mask configurations.
Yes. The Unique Identification Authority of India (UIDAI) and regulatory authorities like RBI recommend sharing masked Aadhaar cards instead of unmasked ones to prevent identity theft.
