Product Introduction

RRB requirements vary by current CEN. This tool applies the appropriate KB ranges and guidance per NTPC (CEN 05/2024) and Level‑1 (CEN 08/2024, 2025/01). Photos follow passport portrait framing (≈35×45 mm). Signatures follow typical 50×20 mm or 140×60 px references. All runs locally in your browser.

Frequently Asked Questions

Which range do I choose?

Pick the exact CEN in the selector; the tool applies corresponding KB ranges for photo/signature.

Do pixel dimensions matter?

Some notices provide 320×240 px or 140×60 px as references; use passport portrait crop for photos and keep signature canvas ratio; ensure clarity and ≥100 DPI if scanned.

What is ‘recent’ for photos?

Varies by CEN (e.g., ≤2 months for Level‑1; ‘recent/latest’ in NTPC). Always check your CEN.

Compliance note: Always follow the current CEN notice for your recruitment.
