Why signatures get rejected and how this fixes it
The most common problems are a grey or shadowed background, a file that is too small (below 10 KB) or too big, and the wrong pixel size. Clean signature fixes the background, the size search keeps the file in range, and the presets set the right pixel size for SSC, IBPS, UPSC, NEET, JEE and PAN applications.

Frequently asked questions
How do I make my signature 10–20 KB?
Choose the photo of your signature, select "Signature 10–20 KB" or your exam preset, and download. The tool keeps it within the range, padding it if it is too small.
How do I get a white background for my signature?
Keep Clean signature switched on. It turns grey paper and shadows pure white and makes the ink dark and crisp.
Which pen should I use?
Most notifications ask for black (sometimes blue) ink on white paper. A gel or felt-tip pen gives a clearer line than a ballpoint.
Can I use a signature in capital letters?
SSC, IBPS and NTA reject signatures in capital letters. Sign in your normal running hand.
