How to prepare

Sign on white paper with black or blue ink.
This is a custom signature preset. Use an official exam preset when available.

Use the right preset before upload

Generic KB tools are useful for quick online forms, but government exam portals often check dimensions, file type, source-specific crop rules and sometimes minimum KB ranges. Keep the custom output label visible unless you switch to an official-source exam preset.

Can I make a signature under 20KB?

Yes, when the source image can be compressed enough. The validation panel shows whether the output passed the selected KB limit.

Does this match SSC or RRB signature rules?

Only after you choose an official SSC, Railway/RRB, UPSC, IBPS, or state exam preset. The generic signature preset is custom.

Finish the rest of the upload workflow

Exam portals often ask for more than one file. Keep moving through the next file type, or switch to a full exam kit when the official preset exists.
