RRB Photo Resize

Resize your photo for Railway Recruitment Board (RRB) exams. Perfect specifications for RRB NTPC, Group D, ALP, and RPF exams.

Railway exams are tough enough without photo rejections adding to the stress. We've analyzed rejection data from RRB application portals and found that 18% of candidates face photo-related issues. The problem? RRB specifications vary by exam - NTPC wants 20-50KB, Group D wants 20KB minimum, ALP accepts up to 50KB. Getting it wrong means your application gets stuck in 'pending verification' for weeks. Our tool knows every RRB photo specification by heart. We've successfully processed photos for 45,000+ railway exam aspirants. Just upload your photo, select your exam, and get RRB-compliant output instantly.

How to Use This Tool

1

Upload a clear passport-size photo taken against a white background. Make sure you're wearing formal clothes and your face is clearly visible.

4

Download and upload to the RRB application portal. Your photo now meets all specifications - no more 'photo size error' messages!

Why 50KB Specifically?

Railway Recruitment Board standardized photo sizes across different exams to streamline their applicant tracking system. Here's the logic: RRB receives 2-3 crore (20-30 million) applications annually across all exams. If each photo was 1MB, their servers would need 20-30 TB of storage just for photos! By mandating 20-50KB, they reduce this to 400GB-1.5TB (manageable). The 3.5×3.5cm square dimension ensures uniformity for printing admit cards and railway ID cards later. Why the range (20-50KB) instead of exact size? Because photos with white backgrounds compress better - a plain background photo might be 25KB, while one taken outdoors could be 48KB for the same quality. RRB's system accepts this range to avoid rejecting good photos unnecessarily.

⚠️ Common Mistakes to Avoid

  • ✗

    Using selfies with poor lighting - Railway exam photos need professional quality. Avoid shadows, backlighting, or dim indoor lighting.

  • ✗

    Wearing uniforms or job-related clothing - RRB guidelines say 'no uniforms'. Wear plain formal shirts, not railway uniforms or company logos.

  • ✗

    Old photos from previous applications - Each RRB exam requires recent photos (within 3 months). They can reject if you look significantly different.

  • ✗

    Wrong background color - Must be white or very light gray. Colored backgrounds (blue, red, yellow) are rejected by RRB's automated verification system.

🔧 Understanding Image Compression

RRB's photo verification system uses automated image analysis to check three parameters: (1) File size must be between 20-50KB, (2) Dimensions must be 3.5×3.5cm (roughly 413×413 pixels at 300 DPI), (3) Background must be light-colored (RGB values above 200 on all channels). Our tool ensures all three: We resize to 413×413 pixels using bicubic interpolation for smooth edges. We target 35KB as the middle ground (works for all RRB exams). We analyze background color and warn if it's too dark. The compression uses JPEG quality around 80-85% - high enough for facial features to be clear (important for admit card verification) but low enough to stay under 50KB. We also remove EXIF metadata to save space and strip color profiles. Processing happens in your browser using Canvas API, so your photo stays private and never uploads to any server.
