300×150px · 10–20 KBHow it works
- Upload a scan or photo of your signature (JPG or PNG, any size).
- We center-crop to 300×150 px on a white background and tune JPEG quality until the file lands between 10 and 20 KB.
- 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

- 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.
