What is the required signature size for JEE Main?

Signatures for JEE Main must be strictly between 4 KB and 30 KB, with dimensions of approx. 350x150 pixels signed clearly in blue or black ink.

Why does the JEE Main portal say "File size is too small"?

The JEE Main portal upload validator filters out images below 10 KB. If your smartphone compressed the photo to below this limit, our tool adds harmless metadata padding to elevate it safely to 20 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.
