Frequently Asked Questions
What does masked mean?
You draw the black boxes yourself — typically over the first 8 digits, leaving the last 4 visible (XXXX-XXXX-1234) per UIDAI convention. Nothing is detected automatically; boxes smaller than 5×5px are ignored. Undo, Clear, and Show/Hide help you review before downloading masked_aadhaar.jpg.
Where is masked Aadhaar accepted?
KYC copies and verifications that don't need the full number.
Is the original safe?
Yes — masking works on a copy; your original scan stays untouched.
Is my document uploaded anywhere?
No — masking runs locally in your browser; unlimited saves on local tools.
