RRB NTPC Undergraduate Signature Size & Live Photo Rules
The RRB NTPC Undergraduate form does not accept a photo file: it takes your photo live with the camera while you fill in the application. You only need to prepare the signature file. Below are the exact sizes from the official notice, tips for the live photo and a free tool that makes the file for you.
RRB NTPC Undergraduate upload requirements
| File | Size (pixels) | File size | Format | Background |
|---|---|---|---|---|
| Photo | Taken live by the camera inside the form — no file | |||
| Signature | 276 × 157 px | 30–49 KB | JPG | White |
The notice does not say whether 1 KB is 1000 or 1024 bytes, so our files fit both ways of counting.
RRB NTPC Undergraduate live photo: how to do it right
- RRB takes your photo live with a webcam or the phone's front camera inside the form. Do not upload or photograph an existing photo.
- Wear dark, non-white clothes so you stand out from the background. Keep the camera at eye level and look straight with a neutral face.
- Keep your whole head and face inside the frame. No cap, mask or glasses. You can preview and retake the photo before you submit.
- The live photo is matched later. If it does not match, you must upload Annexure-IX signed by a Gazetted Officer.
- Keep a colour passport photo, not older than 2 months, for the CBT, document verification and medical.
