RPF Sub-Inspector (SI) Photo & Signature Resizer
RPF (Railway Protection Force) Sub-Inspector recruitment runs on the same centralized RRB application infrastructure as NTPC and Group D, sharing the same photo (20-50KB) and signature (140×60px, 10-20KB) specification. RPF/RRB requires running/cursive handwriting for signatures — block letters or all-capital signatures are strictly rejected. Note that specs have shifted between cycles before (e.g. RPF Constable 2019 allowed 30-70KB, while recent cycles standardized to 20-50KB), so always confirm against the current notification.
| Item | Dimensions | File size |
|---|---|---|
| Photo | 200×230px | 20-50KB |
| Signature | 140×60px | 10-20KB |

Frequently asked questions
Can I reuse a photo prepared for a different exam?
Only if it exactly matches this spec — RPF/RRB portals reject photos even a few KB outside the range or in the wrong format.
Is block-letter signature accepted?
No — RPF/RRB requires running/cursive handwriting; block letters or capital-letter signatures are strictly rejected.
