For the RRB Technician Photo & Signature Size 2026 requirements, candidates do not upload a saved passport photograph. The RRB application portal captures a live photograph during online registration using a webcam or the front camera of a mobile device.

How Your RRB Technician Live Photograph Should Look
Your complete face must remain clearly visible and properly centred inside the live-photo capture frame.
Look straight towards the camera and maintain a natural, neutral facial expression during capture.
Position the webcam or mobile camera at eye level rather than placing it too high or too low.
Do not stand too close to or too far from the camera. Your face should fit naturally within the capture area.
Avoid These Live Photograph Problems
Showing a printed passport photograph to the camera
Showing an existing digital photograph on another screen
Face not fully visible or not centred in the frame
Wearing a cap, mask or spectacles during capture
Standing too close to or too far from the camera
Wearing white clothing instead of non-white or dark clothing
Preview and Retake the Live Photograph
The application system allows candidates to preview the captured photograph and retake it before final submission. Use this opportunity to confirm that your face is fully visible, centred and clearly captured.
Capture the Photograph During Your Application
The RRB Technician live photograph is captured directly inside the official application system. A prepared passport photograph cannot replace this live-camera requirement.
Your Appearance Must Remain Consistent
The live photograph may be validated and matched during the recruitment process. Candidates should maintain a consistent appearance throughout the examination, document verification, medical examination and other recruitment stages.

Prepare Signature →How to Capture RRB Technician Live Photograph 2026
For the RRB Technician 2026 application, the photograph must be captured live through the official RRB application portal. Candidates can use either a computer webcam or the front camera of a mobile device. An existing passport photograph, printed photograph or photograph displayed on another screen must not be used.
Capture Using a Webcam
Open the live-photo capture step on the RRB application portal and allow camera access. Position the webcam at eye level, keep your face centred and capture the photograph directly through the application system.
Capture Using a Mobile Device
Use the mobile-camera option provided by the application system. Capture the live photograph using the front camera while keeping the phone steady and positioned at eye level.
How to Capture an Acceptable RRB Technician Live Photograph
✓ Do
- Keep the camera positioned at eye level.
- Look directly towards the camera.
- Keep your complete face visible and centred.
- Maintain a neutral facial expression.
- Wear non-white, preferably dark-coloured clothing.
- Use clear and even lighting on your face.
- Preview the photograph before final submission.
✕ Don’t
- Do not show a printed photograph to the camera.
- Do not display an existing digital photograph on another screen.
- Do not wear a cap while capturing the photograph.
- Do not wear a mask during live capture.
- Do not wear spectacles during the photograph capture.
- Do not stand too close to or too far from the camera.
- Do not submit a blurred, tilted or poorly centred image.
No Separate Passport Photograph Upload Is Required
The RRB Technician application uses a live-camera photograph instead of asking candidates to upload a prepared passport-style photograph file. Therefore, resizing an old photograph does not replace the official live-capture step.
Preview and Retake the Photograph When Necessary
Review the captured photograph carefully before submitting it. Retake the photograph when the face is blurred, partly outside the frame, tilted, poorly lit or not centred correctly.
Maintain the Same Appearance During Recruitment
The captured photograph may be used to verify the candidate during the examination and later recruitment stages. Candidates should maintain a recognisable and consistent appearance throughout the process.
Prepare the Signature File Before Starting Your Application
The photograph must be captured live, but the signature still needs to be prepared as a JPG or JPEG file between 30 KB and 49 KB with minimum dimensions of 140 × 60 pixels.
Common RRB Technician Photo & Signature Upload Mistakes
Even when the correct file format and size are used, an unclear live photograph or incorrectly prepared signature can still create problems during the RRB Technician 2026 application process. Candidates should preview the live photograph and verify the signature file carefully before submitting the form.
Using the Wrong Signature Size
A signature outside the official file-size, dimension or resolution requirements may fail to upload or may not display clearly.
Check:The signature should be in JPG/JPEG format, between 30 KB and 49 KB, with minimum dimensions of 140 × 60 pixels and minimum resolution of 100 DPI.
Uploading a Saved Passport Photograph
RRB Technician candidates must capture their photograph live through the application portal rather than upload an existing passport-style image.
Check:Use the webcam or mobile front camera provided through the official application workflow.
Showing an Existing Photograph to the Camera
Showing a printed photograph or displaying a digital photograph on another screen does not satisfy the live-photo requirement.
Check:The candidate must appear personally in front of the camera during live capture.
Submitting a Blurred Live Photograph
Movement, poor focus, weak lighting or an unstable camera can make the face unclear and unsuitable for identity verification.
Check:Keep the device steady and retake the photograph when the face is blurred.
Face Not Centred in the Frame
A photograph may be unsuitable when the face is partly outside the capture area or the camera is positioned too high or too low.
Check:Keep the camera at eye level and position the complete face in the centre of the capture frame.
Wearing Restricted Items
A cap, mask or spectacles can prevent the application system from capturing a clear and acceptable live photograph.
Check:Remove the cap, mask and spectacles before starting the live-photo capture.
Wearing White Clothing
White clothing may reduce contrast during live capture and make the photograph less suitable for verification.
Check:Wear non-white, preferably dark-coloured clothing while capturing the photograph.
Writing the Signature in Block Letters
A name written in capital or block letters is not treated as an acceptable running signature.
Check:Use your normal running signature with black ink on clean white paper.
Cutting Off Part of the Signature
Over-cropping can remove strokes from the signature, while excessive white space can make the signature appear too small.
Check:Keep the complete signature visible while removing only unnecessary surrounding space.
Submitting Without Previewing
The live photograph or signature may appear different after capture, resizing, compression or upload.
Check:Preview both items carefully and retake or prepare them again when necessary.
