The free Aadhaar masking tool that protects your privacy
Sharing a full Aadhaar number exposes you to identity fraud. UIDAI recommends sharing a masked Aadhaar where only the last 4 digits are visible. This free tool does exactly that — upload an Aadhaar card image or PDF, and it automatically finds the 12-digit number and blacks out the first 8 digits, leaving the last 4. Everything happens inside your browser using JavaScript and open-source OCR, so your Aadhaar image is never uploaded to any server. If auto-detection misses on a blurry photo, you can draw the mask box yourself. Download the masked image or flattened PDF and share it safely.
Frequently asked questions
Is the Aadhaar masking tool free?
Yes — mask one Aadhaar image or PDF free. The masking runs entirely in your browser with no signup.
Does my Aadhaar get uploaded anywhere?
No. The tool processes your file entirely inside your browser using JavaScript and open-source OCR. Your Aadhaar image or PDF never leaves your device.
How much of the Aadhaar number is masked?
The first 8 digits are blacked out and only the last 4 digits remain visible, following UIDAI's masked-Aadhaar standard.
What if it can't find the number automatically?
You can draw a box over any region of the document manually to mask it, so the tool always works even on blurry photos or scans.
Can I mask an Aadhaar PDF?
Yes. PDFs are rendered, masked and re-exported as a flattened PDF so the hidden digits are permanently removed from the file.
