Mask your Aadhaar number in a PDF
Hide the first eight digits before you share your Aadhaar.
UIDAI recommends sharing a masked Aadhaar, with the first eight digits hidden and only the last four visible, for most verification. This tool lets you black out those digits and permanently remove them on export, all in your browser so your Aadhaar is never uploaded.

Why mask Aadhaar on your device
Your full Aadhaar number is sensitive. Masking it in the browser means the unmasked document is never uploaded, so there is no copy of your full number on someone else’s server.
Frequently asked questions
Why mask only the first eight digits?+
UIDAI’s masked Aadhaar shows only the last four digits, which is enough for many purposes while keeping the full number private.
Is the number truly removed?+
Yes. On export the digits under the box are deleted, so they cannot be recovered from the file.
Is my Aadhaar uploaded?+
No. The masking runs entirely in your browser, so your Aadhaar never reaches a server.
Is it free?+
Yes, with no sign-up.
