About Mask Aadhaar
Mask Aadhaar finds the 12-digit number on your card, covers the first 8 digits with a black box and leaves the last 4 visible, like an official masked Aadhaar. The text is read on your device, so your card is never uploaded. You can add or remove boxes by hand before you save.

Frequently asked questions
Is my Aadhaar uploaded anywhere?
No. The number is found on your device and the masked file is created there too.
What if the number isn't found automatically?
Drag a box over the digits yourself. Blurry or tilted photos are the usual reason.
Is the covered part really hidden?
Yes. The black boxes are drawn into the saved image, so the digits underneath are gone. Always check the result before sharing.
Are my files uploaded anywhere?
No. This tool runs in your browser, so your file stays on your device and is never sent to a server.
