RRB Group DPhoto & Signature Upload Requirements Guide

The Railway Recruitment Board Group D Level 1 Exam (RRB Group D) mandates that every candidate upload a strictly compliant passport-style photograph and a handwritten signature during online registration. Non-compliant files are among the most common reasons for form rejection before the application is even reviewed. For the RRB Group D photo size, the required pixel dimensions are 320 x 450 pixels, with a file size between 20 KB and 50 KB in JPEG format. The background must be plain white. The RRB Group D portal does not require any printed text overlay on the photograph. For the RRB Group D signature size, your handwritten signature on white paper must be scanned or photographed to produce an image of 140 x 60 pixels, compressed to 10–30 KB. Signatures must be written using black ink and must not be in capital letters. Our free online RRB Group D photo resize tool compresses and crops both files locally inside your browser — your images are never uploaded to any server. Specifications are sourced directly from the 2026 Notification and last verified on 2026-04-18.
