What is the required signature size for Aadhaar Card?

Signatures for Aadhaar Card must be strictly between 20 KB and 1024 KB, with dimensions of approx. 400x200 pixels signed clearly in blue or black ink.

Why does the Aadhaar Card portal say "File size is too small"?

The Aadhaar Card portal upload validator filters out images below 50 KB. If your smartphone compressed the photo to below this limit, our tool adds harmless metadata padding to elevate it safely to 60 KB without blurring your face.

Are candidate photos uploaded to your servers?

Never. All image processing takes place 100% inside your web browser. Zero bytes are uploaded to our servers, preserving your confidential identity data.
