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