About the Aadhaar Masking Tool
A masked Aadhaar shows only the last 4 digits of your 12-digit Aadhaar number — UIDAI itself recommends sharing the masked version wherever full Aadhaar is not legally required, such as hotel check-ins, SIM verifications, rental paperwork and courier KYC. Most people either share the full number (risky) or upload their card to a random website or app to hide it (riskier). This tool does the masking entirely on your device: the photo of your card is opened in your browser, you drag a black box over the first 8 digits, and a fresh masked copy is saved. Nothing is ever uploaded to ToolSetu or anyone else.
Because the masked image is re-exported as a brand-new picture, the covered digits are physically gone from the file — unlike a sticker or annotation layered on a PDF, there is nothing underneath to recover.
How to use it
- Take a clear photo or screenshot of your Aadhaar card and drop it into the box above (JPG, PNG or WebP).
- A black box appears near where the Aadhaar number usually sits — drag it precisely over the first 8 digits, and drag the round corner handle to resize it.
- Add more boxes if you also want to hide other details (for example the QR code or address on the back).
- Choose JPG or PNG and press Download — the masked copy is saved instantly to your device.
Why mask your Aadhaar — and why in the browser?
Your Aadhaar number is a lifetime identifier — once a full copy leaks, you cannot change it the way you change a password. Masked Aadhaar (last 4 digits visible) is accepted for most everyday identity checks, so sharing the masked version is simply good hygiene. The catch: most online "mask Aadhaar" services make you upload the card image to their server — exactly the document you are trying to protect. This tool never transmits your card anywhere; you can even switch on flight mode after the page loads and it will still work. The output is a flattened image, so the blacked-out digits are unrecoverable.
Common uses: sending ID proof to a landlord or broker for a rent agreement, hotel and travel bookings, courier and delivery KYC, attaching ID to an RTI application, or sharing with an employer for verification.
Frequently asked questions
Is my Aadhaar card uploaded to any server?
No. The photo is opened and masked entirely inside your browser using the canvas on this page. ToolSetu never receives the image — you can verify this by turning on flight mode after the page loads; masking and download still work.
Can the blacked-out digits be recovered from the downloaded image?
No. The download is a freshly drawn copy of the image with solid black rectangles baked into the pixels. There is no hidden layer underneath, unlike annotations placed on top of a PDF.
Is a masked Aadhaar legally valid as ID proof?
For most everyday verifications — hotels, travel, rentals, couriers — a masked Aadhaar showing the last 4 digits is acceptable and is what UIDAI recommends sharing. Banks, telecom and government processes that legally require full Aadhaar will still ask for the unmasked version through their official channels.
I have an e-Aadhaar PDF, not a photo. How do I mask it?
Convert the PDF page to an image first with the free PDF to JPG tool on ToolSetu (also fully in-browser), then drop that image here and mask it.
Which parts of the card should I hide?
Hide the first 8 digits of the 12-digit number — keep the last 4 visible so the document remains identifiable. Many people also mask the large QR code, since it encodes your demographic details; add a second box for it.
