RRB NTPC upload requirements are not universal across every recruitment cycle. The current CEN 06/2026 and CEN 07/2026 notices use live-photo capture and a scanned JPG/JPEG signature between 30KB and 49KB with minimum 140 x 60 pixel dimensions. Do not reuse an older photo or signature limit for a new CEN.
