RRB Technician Photo and Signature Size 2026: Image Format, Dimensions & Upload Guidelines

The Railway Recruitment Board (RRB) has prescribed specific guidelines for uploading photographs and signatures during the RRB Technician 2026 application process. Candidates must strictly follow these specifications, as any incorrect image format, file size, unclear photograph, or invalid signature may lead to rejection of the application.

The uploaded photograph and signature are used to verify a candidate's identity throughout the recruitment process, including the written examination, document verification, medical examination, and final appointment. Understanding the official image requirements before applying helps candidates avoid common mistakes and complete the application without complications.

RRB Technician Image Upload Guidelines

The RRB Technician application process requires specific procedures for candidate images. It is important to note that photos are captured live, not uploaded.

Live Photo Capture for RRB Technician Application

Candidates do not upload a pre-existing photograph. The application system captures a live photo. Use a webcam or your mobile phone's front camera for this.

 Key guidelines for live photo capture:

• Position the camera at eye level.

• Sit or stand directly in front, looking straight.

• Maintain a neutral facial expression.

• Ensure your entire face is clearly visible and centred.

• Avoid wearing caps, masks, or glasses/spectacles.

• Wear non-white clothing, preferably dark, for good contrast.

• Preview your photo. Retake it if you are not satisfied.

 Applications with photos that do not meet these standards are rejected. Your appearance throughout the recruitment process must match the photo captured.
