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.

Forms using this size

  • SSC
  • RRB NTPC
  • RRB Group D
  • IBPS PO / Clerk
  • State PSC forms

Getting the scan right

  • 10–20 KB is a narrow window — start from a clean, high-contrast scan rather than a dim phone photo.
  • Crop tight around the signature before uploading. Empty white margins waste your KB budget.
  • If the result looks faded, re-scan with more contrast rather than lowering the target size.
