Railway Signature Resizer
Indian Railways online recruitment runs through Railway Recruitment Boards (RRBs). For CEN No. 06/2025, the signature upload rules in para 14.5.1 match the RRB NTPC graduate notification: JPG/JPEG, minimum 140 × 60 pixels, 100 DPI scan, 35 mm × 20 mm box, black ink, running handwriting. Group D, ALP, and other CENs may reuse similar signature mechanics but can differ — open the PDF for the CEN number shown on your application link, not an older blog post. Live photo capture replaced pre-uploaded photographs in recent CENs; focus your preparation time on a clean signature scan that will match exam-day verification.
