How it works

  1. Upload a scan or photo of your signature (JPG or PNG, any size).
  2. We center-crop to 300×150 px on a white background and tune JPEG quality until the file lands between 10 and 20 KB.
  3. Download and upload it straight to the form.

Everything runs on your device — your signature is never sent to a server.

Getting the scan right

  • Sign with a black or dark blue pen on plain white paper, then scan or photograph it in daylight.
  • Do not sign in capital letters — SSC treats a block-letter signature as invalid.
  • The signature on the admit card must match the one you sign in the exam hall, or your paper is cancelled.
  • Scan at 200 DPI or higher before resizing, so the strokes stay sharp after compression.

Frequently asked questions

What is the signature size for SSC?
SSC requires a JPEG signature of 300×150 pixels, between 10 KB and 20 KB.
Why does SSC reject my signature upload?
Almost always the file is over 20 KB, or the background is grey instead of white. This tool fixes both in one step.
Is my signature uploaded to a server?
No. ShantiTools processes the image entirely inside your browser — the file never leaves your device.
