Make your RRB signature in 30-49 KB and test your live photo before you face the camera.
Last updated:
RRB now takes your photo live from the camera, so there is no photo file to upload. Use the second box to practise: it checks background, light and blur.
Tap a card to get that file ready
From RRB CEN 06/2026 and 07/2026, as reported by PW and Oliveboard. Check your CEN on rrbapply.gov.in before you submit.
The minimum is 30 KB, and most free tools make the signature too small. This one raises it to the minimum safely.
| File | Format | Size | How |
|---|---|---|---|
| Photograph | No file | Set by the portal | Live capture with webcam or phone front camera |
| Signature | JPG / JPEG | 30-49 KB | Upload, at least 140 × 60 px |
| SC/ST certificate | As shown on the form | Only if you claim free travel |
From RRB CEN 06/2026 and 07/2026, as reported by PW and Oliveboard. Each RRB notice (CEN) can change this, so check yours.
Use the practice box above. It reads your selfie and tells you what to fix.
| Check | Do this |
|---|---|
| Background | Stand in front of a plain white or off-white wall |
| Clothes | Wear dark or coloured clothes, not white |
| Light | Face a window or a bright light; no light behind you |
| Face | Look straight at the camera, both eyes open, neutral face |
| Headwear | No cap, mask or tinted glasses; religious headgear is fine if the full face shows |
| Phone | Hold it at eye level and keep it still |
| Network | Use a steady connection so the capture does not time out |
Live photo rules from PW and Oliveboard. If the background check fails here, it will look poor on the form too.
The tool makes 350 × 200 px, which keeps the 35:20 shape and is well above the 140 × 60 minimum.
Many railway aspirants also fill IBPS and SBI forms. The rules are very different.
| Upload | RRB | IBPS / SBI |
|---|---|---|
| Photo | Live capture, no file | File, 20-50 KB |
| Signature | 30-49 KB | 10-20 KB |
| Left thumb | Not asked | 20-50 KB |
| Handwritten declaration | Not asked | 50-100 KB |
For bank forms, use the IBPS Document Resizer. Do not reuse your RRB signature file: it is above the bank limit.
| Problem | Fix |
|---|---|
| Signature under 30 KB | The tool raises it above 30 KB |
| Signature over 49 KB | The tool keeps it under 49 KB |
| Signature in capital letters | Sign again in running hand |
| Blue ink or ruled paper | Use a black pen on plain white paper |
| Live photo too dark | Face a window; check it in the practice box |
| Wearing white clothes | Change to a dark top |
| Captured a printed photo | Not allowed; capture your real face |
Everything runs in your browser. Nothing is uploaded or saved.
There is no photo file now. RRB captures your photo live through the webcam or phone front camera inside the form, so no KB or pixel size applies.
A JPG of 30-49 KB, at least 140 x 60 pixels, signed in running hand with a black pen inside a 35 x 20 mm box on white paper.
The minimum is 30 KB. A plain signature is usually smaller. This tool raises the file above 30 KB without changing how it looks.
Tinted glasses are not allowed. Some guides say no spectacles at all, so remove clear glasses too if you can see the screen without them.
Dark or coloured clothes. White clothes blend into the white background.
Yes, the front camera works. Keep the phone at eye level, face the light and hold still.
No. It only checks the photo inside your browser. Nothing is uploaded or saved.
No. Only SC/ST candidates claiming free railway travel upload it, in the format given in the notice.
Not as it is. Bank exams want 10-20 KB. Make a new file with the IBPS Document Resizer.
