Aadhaar Number Masker
Mask the middle 8 digits of your Aadhaar (XXXX XXXX 1234), or draw redactions on an Aadhaar card image. UIDAI-recommended format. Runs entirely in your browser — image never uploaded; EXIF stripped.
Format follows the UIDAI masked-Aadhaar convention: first 8 digits hidden, last 4 shown.
About this tool
The UIDAI itself recommends sharing a masked Aadhaar — first eight digits hidden, last four visible — anywhere the verifier does not legally need your full 12-digit number. Hotels, couriers, attendance registers, gym memberships, society visitor logs all accept masked Aadhaar as ID proof. UIDAI even issues an officially-signed masked Aadhaar PDF directly from the mAadhaar app and DigiLocker.
This tool runs entirely in your browser. In text mode, paste your number and copy the masked version. In image mode, drop a photo or scan of your Aadhaar card and drag rectangles over each region you want hidden — the number itself, the QR code, the address, the photograph. The output is downloaded as a fresh JPG with the masks permanently baked into the pixel data and all original EXIF, GPS, and camera metadata stripped (a side-effect of the canvas re-encode).
For higher-security KYC, prefer VID (Virtual ID) — a 16-digit revocable token generated from your Aadhaar that regulated KYC entities accept in lieu of the full number. VID and masked Aadhaar serve different roles: VID for verification, masked Aadhaar for casual ID proof.
How to use (5 steps)
- Pick a mode. Text mode — for sharing the number itself. Image mode — for sharing a photo/scan of the card.
- Text: paste number. Type or paste your 12-digit Aadhaar. Spaces and dashes are auto-stripped. Output appears as XXXX XXXX 1234.
- Image: upload card. Image mode: drop a JPG/PNG of the Aadhaar card. The file stays in your browser; nothing is uploaded.
- Image: draw rectangles. Drag rectangles over each region you want hidden — the number, photo, QR code, address, whatever. Use Undo / Reset as needed.
- Download. Click 'Mask & download JPG'. The output is a fresh JPG with redactions baked in and all EXIF / GPS / camera metadata stripped.
Frequently asked questions
+−When should I share masked Aadhaar instead of the full one?
UIDAI explicitly recommends sharing masked Aadhaar (last 4 digits visible) any time the recipient does not legally need your full 12-digit number — for example: hotel check-ins, courier/parcel acceptance, attendance proofs, gym/club enrolment, society registers. Use full Aadhaar only for KYC where the verifier is a regulated entity (banks, telecom, govt agencies) and is OTP- or biometric-verifying you online.
+−Is masked Aadhaar legally valid?
Yes, for non-KYC purposes. UIDAI itself issues a 'masked Aadhaar' download option in mAadhaar / DigiLocker / UIDAI website — the document is officially signed and serves as ID proof in many contexts (rail/air travel ID, hotel stays, etc.). For Banking/SIM/Govt KYC, however, regulated entities require full Aadhaar via Aadhaar e-KYC or offline XML, not a masked image.
+−Why mask Aadhaar at all?
Your full Aadhaar number, paired with biometric or OTP, can be used to authorise transactions and KYC in your name. A photocopy of your Aadhaar in the wrong hands has been linked to identity-theft cases (forged loans, SIM-cloning, fake KYC). Masking the first 8 digits preserves the document's identification value while removing the most sensitive component.
+−Should I use VID instead?
VID (Virtual ID) is a 16-digit revocable token UIDAI generates from your Aadhaar — even better than masking for KYC. Generate it on resident.uidai.gov.in or via SMS. Use VID where the recipient supports it (most regulated KYC entities do); use masked Aadhaar everywhere else (hotels, courier, etc.). The two are complementary.
+−Does this strip EXIF metadata?
Yes — the image mode re-encodes your file as a fresh JPG via the browser's canvas API. Canvas-exported blobs do not carry over EXIF, GPS coordinates, camera info, or any other metadata from the original file. The only thing preserved is the visible pixel data (with your masks applied).
+−Can I use this to mask other ID cards?
Yes. The image mode is generic — it lets you draw black (or any colour) rectangles over any region of any image and download a re-encoded copy with those areas permanently filled. Use it on PAN cards, driving licences, passports, voter IDs, bank statements — anything with sensitive data you want to redact before sharing.
+−Is the masked file actually safe? Can someone recover the data?
Yes, it's safe. The black rectangle is baked into the JPG pixel data — the original pixels under the rectangle are gone, not just hidden by an overlay. There is no Photoshop-style 'layer' that someone can peel off. (Compare to PDF redaction tools that sometimes only hide layers — those are unsafe.) Always download and inspect the output before sharing.
