Signature Resize 30 KB to 50 KB (RRB, UP Police)
Railway and UP Police forms want a bigger signature file: at least 30 KB. A tiny 140×60 signature can never reach that honestly, so the presets use larger pixels with the same shape.

Which forms ask for this size
| Form / exam | Rule | Guide |
|---|---|---|
| RRB NTPC | 30–49 KB, at least 140×60 px | RRB NTPC guide |
| RRB ALP | 30–49 KB | RRB ALP guide |

Tips for a file that gets accepted
- RRB says 30 KB to 49 KB: a 50 KB file is rejected, so the RRB preset stops at 49.
- Never add noise or blur to reach 30 KB; use larger pixels or a darker pen instead.
