Railway recruitment forms ask for a scanned signature, while the photograph is captured live in recent cycles. Resize your RRB signature to the exact size below.
RRB (NTPC / Group D / JE / ALP) photo and signature requirements

Photo is captured live in recent cycles. Reported signature limits differ (30–70 KB), so 30–50 KB is used to pass either.
Tips to avoid rejection
- Sign in black ink on white paper in running (cursive) letters, not block or capital letters.
- Keep the signature inside a 50 mm × 20 mm box, about 140×60 pixels.
- Reported limits differ between notices (30 to 70 KB for JE, 30 to 50 KB for Group D), so this tool uses 30 to 50 KB, which passes both.
