240×120px · 610 KB

How it works

  1. Upload a scan or photo of your signature (JPG or PNG, any size).
  2. We center-crop to 240×120 px on a white background and tune JPEG quality until the file lands between 6 and 10 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

  • Older state government portals
  • Some RRB forms

Getting the scan right

  • At 10 KB, contrast matters more than resolution. Scan in black and white mode if your scanner supports it.
  • Trim white space aggressively — at this size every kilobyte counts.

Frequently asked questions

Will my signature still be readable at 10 KB?
Yes, if you start from a high-contrast black-ink scan. We keep the pixel dimensions modest so the strokes stay solid.
Is my signature uploaded to a server?
No. ShantiTools processes the image entirely inside your browser — the file never leaves your device.
