A practical working band is about 10–40 KB at roughly 3.5 × 1.5 cm JPG — confirm the latest CEN PDF for your window.

1. Sign on white paper with black/blue ink.
2. Open Signature tool.
3. Crop so the ink fills most of the box.
4. Compress into the allowed KB range and Free Download.

Photo / “section controller image” resizer

Queries like RRB section controller image and photo resizer RRB Section Controller map to the photograph upload. Use the Photo tool for about 20–50 KB, portrait crop (~3.5 × 4.5 cm). Live-photo CENs may capture the face via webcam instead — in that case you still often upload a scanned signature separately, so keep the signature pack ready.

Live photograph vs uploaded photograph

Newer Railway CENs sometimes require a live photograph captured during application (webcam / app). If your CEN says live photo is mandatory, do not upload an old gallery shot for that field. Still use Size to KB for the signature (and any other scanned documents the form lists).
