The Railway Recruitment Board (RRB) conducts exams for some of the largest recruitment drives in the country, including Non-Technical Popular Categories (NTPC), Assistant Loco Pilot (ALP), Group D and Junior Engineer (JE). With crores of applicants competing for these positions, RRB's application portal is unusually specific about photograph requirements — not just the pixel size and file weight, but also the background color, which must be plain white. This tool resizes your photo to the exact 350×450 pixel RRB standard and compresses it into the 30KB to 70KB band, entirely inside your browser.
RRB Photo & Signature Specification
| Item | Dimensions | File Size | Format / Background |
|---|---|---|---|
| Photograph | 350×450 px (35mm × 45mm) | 30KB – 70KB | JPEG, white background required |
| Signature | 500×200 px (50mm × 20mm) | 30KB – 70KB | JPEG, black or blue ink |
This specification applies uniformly across RRB NTPC, ALP, Group D and JE recruitment. The white background requirement is strictly checked — a photo taken against a wall, curtain or outdoor setting, even if otherwise correctly sized, is one of the most frequent reasons for rejection at the document verification stage.
How to Resize Your RRB Photo — Step by Step
- Take or upload a photo against a plain white background, then upload it in the Photo tool above.
- The tool locks the output to 350×450px (35mm × 45mm), the standard RRB photo size.
- Click Resize Image — it automatically compresses the JPEG to fall between 30KB and 70KB.
- Repeat for your signature using the Signature tool, which targets 500×200px (50mm × 20mm).
- Download both files and upload them during RRB online application.
Common Mistakes That Cause Rejection
- Non-white background — a colored wall, curtain or outdoor background is one of the top reasons RRB applications get flagged during scrutiny.
- Wrong aspect ratio — RRB's 350×450px size is not a square like SSC or Aadhaar; uploading a square photo without correcting the ratio can distort the face.
- File size outside 30KB–70KB — an unedited phone photo is almost always several megabytes and needs proper compression, not just a smaller crop.
- Signature scanned at the wrong aspect ratio — the 500×200px signature box is wide and short; a square signature scan gets stretched awkwardly when resized without adjustment.
- Using an old photo — RRB recommends a recent photograph; using an old ID-style photo can cause a mismatch during physical verification or biometric checks.
Why the White Background Rule Exists
Railway recruitment involves multiple rounds of identity verification — at the exam centre, during document verification, and again during medical examination for safety-critical roles like Loco Pilot. A uniform white background makes it easier for verification staff to compare the uploaded photo against the candidate in person and against other ID documents, which is why RRB enforces this rule more strictly than most other exam bodies.
