Mask Aadhaar Card
UIDAI recommends hiding the first 8 digits of your Aadhaar when sharing a copy. Upload your Aadhaar image, drag a box over the digits, and download a masked version — everything stays in your browser, nothing is uploaded.
How to mask your Aadhaar number before sharing
- Upload a photo or scan of your Aadhaar card.
- The tool covers the first 8 digits, leaving only the last 4 visible.
- Download the masked copy and share that instead of the original.
Why mask it
UIDAI allows the first 8 digits of the Aadhaar number to be hidden when Aadhaar is used as proof of identity or address. Sharing a fully visible number more widely than needed raises the risk of misuse.
What stays visible
The last 4 digits, your name, photo and other details remain readable, which is enough for most verification purposes. Only share a masked copy where the recipient accepts it.
This runs on your device
The image is never uploaded, so your Aadhaar does not pass through any server while you mask it.

Frequently asked questions
Is it legal to mask my Aadhaar number?
Yes. UIDAI itself recommends masking the first 8 digits of your Aadhaar when sharing a copy, so that only the last 4 digits are visible. This tool only helps you cover the digits you choose on your own document.
Is my Aadhaar image uploaded anywhere?
No. Everything happens in your browser. The image is never uploaded to a server, never stored, and never sent anywhere.
How do I mask my Aadhaar card?
Upload your Aadhaar image, then drag a box over the first 8 digits to cover them with a solid black bar. Add more boxes if needed, then download the masked JPG.
Can the masked digits be recovered from the downloaded image?
No. The tool draws a solid bar directly onto the image pixels and exports a flattened JPG, so the covered digits are not present in the saved file.
