Requirements

Digital Signature Requirements (30 KB)

IBPS, SBI, RBI, and NTA exam portals require a scanned signature at 140 x 60 px, JPEG format, under 30 KB. This is the standard bank and education exam signature specification.

Dimensions
140 × 60 px
Format
JPEG
Max file size
30 KB
Resolution
96 DPI
Background
Plain white paper only. No grid paper, letterhead, or coloured backgrounds.

Additional requirements

  • Sign with a dark blue or black pen. The bank portal will display this image on the admit card and hall ticket, so clarity matters.
  • Scan the full page first, then crop to just the signature leaving a small white border on all sides.
  • Photograph in even, bright lighting if a scanner is not available. No shadows or glare on the signature.
  • Remove any dotted or ruled lines from the page before scanning, or use plain paper from the start.
  • Your signature on the portal must match what you sign on the application form and at the examination centre.

Troubleshooting

Common issues & fixes

If your upload is rejected, one of these is usually the reason.

  • Signature file exceeds size limit

    What you see

    Portal shows "Signature file size must be under 20 KB" or similar.

    How to fix it

    This tool automatically compresses your signature to under 20 KB. Re-process and download again.

  • Background not white or off-white

    What you see

    Portal rejects the signature or the preview shows a coloured/dark background.

    How to fix it

    Sign on a clean sheet of plain white paper. Avoid ruled notebooks or coloured paper. Photograph in bright, even lighting (no shadows over the signature).

  • Signature is too faint or not legible

    What you see

    Automated check flags "Signature not detected" or the scanned signature is barely visible.

    How to fix it

    Use a black or dark blue ball-point or gel pen. Avoid felt-tip pens that bleed. Make sure lighting is even and there are no shadows across the signature.

  • Signature dimensions rejected

    What you see

    Portal shows "Signature must be 140 × 60 pixels" or similar dimension error.

    How to fix it

    This tool resizes your signature image to exactly 140 × 60 pixels. Use the processed download, not your original scanned file.

  • Lines or marks around the signature

    What you see

    The portal or verifier flags "Signature contains ruled lines or marks".

    How to fix it

    Sign on blank white paper, not on a ruled or printed page. Leave at least 1 cm of blank white space on all sides of your signature before scanning or photographing.
