Mask your Aadhaar card PDF

How to mask an Aadhaar PDF

1. Choose or drop the e-Aadhaar PDF. Its password is the first four letters of your name in capitals followed by your birth year, such as SURE1990.
2. Aadhaar numbers, phone numbers and dates are already selected. Click any text to hide or show it.
3. Draw a box over the photo and QR code: they hold your details too.
4. Download, then check the copy before you send it.

Good to know

• UIDAI's own masked Aadhaar shows the last four digits. Here the whole number is hidden unless you click it to show it.
• Redacting removes UIDAI's digital signature, so the copy can't be verified as an original. That is expected for a shared copy.
• Scanned Aadhaar cards have no text to search. Draw boxes over the number instead.

Why this is real redaction

• Drawing a black box in a PDF editor leaves the text underneath; anyone can copy it out. Here the hidden text is deleted from the file.
• The rest of each page keeps its original text, so it stays sharp, selectable and searchable instead of turning into a blurry image.
• After export the PDF is read back like any PDF reader would. If hidden text could still be extracted from a page, that page is saved as an image instead.
• Comments, form fields, thumbnails, bookmarks, attachments and document metadata are removed.
• The site has no server code, no analytics and no cookies. Its security policy stops the page from connecting to any other site, and it keeps working offline after the first visit.

Questions

What is the password of an e-Aadhaar PDF?

The first four letters of your name as printed on the card, in capitals, followed by your year of birth, for example SURE1990.

Is it safe to mask Aadhaar online?

Here nothing is uploaded: the PDF is opened and masked inside your browser tab, and the site works offline once loaded.

Can someone copy the text from under the black bars?

No. Hidden text is deleted from the PDF itself, not just covered. After export the file is re-read, and any page where hidden text could still be extracted is saved as an image instead.
