How to make your JEE Main Signature in 4 steps

Sign on plain white paper in the ink colour your form asks for (usually black), keeping the signature inside a small box.
Photograph or scan the signature in even light, with no shadows across the paper.
Pick the image in the tool, tap "Make paper white" if needed, then use Zoom and Move to crop tightly around the signature box.
Check that the size and file size lines show ✅ (10 to 100 KB), then tap Download and upload the JPG.

Common reasons this signature is rejected

A file over 100 KB or under 10 KB.
A faint scan that is hard to read after compression.
Uploading someone else's signature, which NTA treats as unfair means.
