Aadhaar and PAN numbers are commonly required as proof of identity, but the full number doesn't need to be visible to whoever you're sending the document to — a bank, employer, or portal usually only needs to confirm the document type, not read every digit. UIDAI itself recommends masking Aadhaar numbers, showing only the last 4 digits, whenever a physical or scanned copy is shared for a purpose that doesn't strictly require the full number.
This tool detects the number pattern on the image and covers it with a solid black bar, leaving the rest of the document untouched and legible. Because it runs locally in your browser, the original ID image and the masked copy both stay on your device — nothing is sent to a server in the process, which matters given how sensitive these documents are.
For documents going to a government portal that explicitly requires the full unmasked number, don't mask it — check the specific requirement first, since masking an ID that needs full verification will get your submission rejected.
No — this runs locally in your browser, which matters especially for signed or sensitive documents.
The tool performs the technical operation correctly; whether a signature or redaction meets a specific legal/portal requirement is worth double-checking against that requirement.
Detection is automatic, but always double-check the masked image before sending it — automatic masking can occasionally miss a digit if the scan is angled or low-contrast, so a quick visual check is worth the ten seconds.
Yes, it detects both the 12-digit Aadhaar number pattern and the 10-character PAN format and masks accordingly.
