Mask your Aadhaar before you share it.
Drag a box over the first 8 digits of your Aadhaar number — or anything else you want hidden — and download a masked copy. UIDAI recommends sharing a masked Aadhaar, and most exams accept it as ID proof. Done entirely in your browser; your Aadhaar is never uploaded.
Why mask your Aadhaar
A masked Aadhaar hides the first eight digits and shows only the last four, which is enough to act as identity proof while protecting your full number. UIDAI itself promotes masked Aadhaar for exactly this reason. When a form asks for an ID copy and you don’t want your full number floating around a portal, upload a masked version.
Why doing it in the browser matters
Most “mask Aadhaar” websites ask you to upload your Aadhaar to their server — the opposite of safe. CorrectForm masks the image on your own device using the HTML Canvas API. Nothing is uploaded, stored, or logged; you can confirm it in your browser’s DevTools → Network tab.
Frequently asked questions
- Why mask the first 8 digits of an Aadhaar number?
- A masked Aadhaar shows only the last 4 digits, which UIDAI recommends when sharing copies. Masking before you upload to an exam or job portal limits what can be misused if the copy leaks.
- Is the masking permanent in the downloaded file?
- Yes — the pixels are painted over in the exported image. It is not a removable layer, so the digits cannot be recovered from the file.
- Can I mask other details too?
- Yes — drag a box over anything (QR code, address, phone number). You can add several boxes and undo any of them before exporting.
- Is my Aadhaar card uploaded to a server?
- No — this is the whole point of the tool. The image is processed entirely in your browser and never transmitted, stored, or logged.
