RRB Group D 2026 Photo Size & Upload Rules

All major Railway exams, including RRB Group D and NTPC, share strict limits that require custom formatting to avoid rejection.

RRB Group D Document Specifics

All Railway exams (RRB NTPC, Group D, ALP, JE, Technician, RPF) use the same photo and signature specifications[cite: 9]. You can prepare these documents once and reuse them across all Railway applications.

RequirementPhotoSignature
Pixel Dimensions200 × 230 px140 × 60 px
Maximum File KB20 – 40 KB5 – 15 KB
⚠️ The 40 KB Trap: While SSC allows files up to 50 KB, RRB has a 40 KB photo limit[cite: 9]. This is a common mistake — aspirants use their 48 KB SSC photo for RRB Group D and get rejected immediately[cite: 9]. Always re-compress specifically for Railway forms.

How to Hit 40KB Perfectly

  1. Navigate to the ExamReady Photo Resizer.
  2. Select the RRB-specific 200×230 px preset[cite: 9].
  3. Upload your image. The tool utilizes an algorithm designed to compress your file as close to 40 KB as possible without sacrificing clarity[cite: 9, 15].
  4. Ensure your signature scan is clean and the background is white, as grey backgrounds bloat file size and make hitting the tiny 15 KB limit difficult[cite: 9].
