RRB Group D 2026 Photo & Signature Size — Complete Upload Guide

Railway recruitment under RRB Group D sees millions of applicants every cycle — and thousands of applications get flagged for incorrect photo or signature uploads. Here are the exact specs and how to get them right in under 2 minutes.

RRB Group D 2026 photo and signature specs

| Document | Dimensions | File size | Format | Background | |---|---|---|---|---| | Photograph | 320 × 240 px | 20 KB – 50 KB | JPG | Plain white | | Signature | 140 × 60 px | 10 KB – 40 KB | JPG | Plain white |

Note: RRB Group D uses a landscape photo format (320 × 240 px, wider than tall) — the opposite of most other exams. This catches a lot of candidates off-guard.

Always verify against the official RRB notification for the current recruitment cycle before submitting.

Step-by-step upload

1. Take your photo

- Plain white background — no off-white, no gradients - Face and shoulders visible, face occupying 70–80% of the frame - Passport-style, front-facing, neutral expression - Taken within the last 6 months — old photos get rejected at document verification - No sunglasses, caps, or heavy headwear

2. Resize to 320 × 240 px

Use our RRB Group D Photo Resizer. It crops to the exact landscape dimensions and compresses the JPG to land within 20–50 KB automatically.

3. Sign on plain white paper

- Use a black or dark-blue ballpoint pen - Photograph or scan in good lighting, no shadows or folds - Crop tightly — the signature area is small (140 × 60 px), so stray whitespace eats into the signature itself

4. Resize signature to 140 × 60 px

Use our RRB Signature Resizer. At 140 × 60 px, the signature box is very small — make sure the original photo of your signature is close-up and in focus.

5. Upload on the RRB portal

- Navigate to the active RRB Group D recruitment → online application - Photo upload comes first, then signature - Check the preview after each upload — if the image looks stretched or pixelated, re-upload with the correct file

Common RRB Group D upload errors

Photo is portrait instead of landscape

Most exam photos are taller than wide (portrait). RRB Group D's 320 × 240 px is landscape (wider than tall). If you upload a portrait-cropped photo, the portal may accept it but the image will appear distorted in your application form.

Fix: Our resizer handles the landscape crop automatically.

Photo is too dark or too bright

Railway portals flag photos where the face isn't clearly lit. Take the photo near a window in natural light, facing the light source — not with it behind you.

File size over 50 KB

Phone cameras produce 3–5 MB photos. Even after resizing to 320 × 240 px, JPEG quality might still be too high. Our resizer binary-searches the JPEG quality until the file lands under 50 KB.

Signature too small to read

At 140 × 60 px the signature box is tiny. If your original signature photo isn't close-up, the resized version will be unreadable. Re-sign on a clean sheet, photograph just the signature, and then crop it tightly before resizing.

Wrong format (PNG instead of JPG)

RRB portals explicitly reject PNG files even if the dimensions are correct. Always save as JPG.
