SSC Signature Resizer — Free 140×60 px, 10–20 KB Signature for SSC Forms

Resize your SSC signature to exactly 140 × 60 pixels and between 10 and 20 KB — the official specification for SSC CGL, CHSL, GD Constable, MTS and Steno applications. Bulk mode handles many applicants at once, and your signature never leaves your browser.

How to resize your signature for an SSC application

1. Sign on plain white paper with a black ink pen, in running hand (not capitals), and scan or photograph the signature.
2. Drop the scan into the box above — keep the SSC Signature mode: 140 × 60 px, 10–20 KB.
3. Click Resize for SSC and download the form-ready JPEG. Upload it on the SSC portal.

Why SSC forms reject signature uploads

SSC upload forms run two hard checks, and a phone-camera photo fails both. The first check is dimensions: the official specification asks for 140 × 60 pixels (preferred) for the signature image. A scan from a phone is typically 3000+ pixels wide. The second check is file size: the official specification requires the file to be between 10 KB and 20 KB — not smaller, not larger. A phone photo is usually 1–5 MB, hundreds of times over the limit. Shrinking the picture in a gallery app only fixes the pixel dimensions; compressing it in a generic tool only fixes the kilobytes. If the size still lands outside the window — too small or too large — the form rejects it again. This resizer does both jobs in one pass: it fits your full signature (never cropping, so no stroke is lost at the edges) onto the exact 140 × 60 canvas with a white background, then binary-searches JPEG quality until the file lands inside the 10–20 KB window, keeping the sharpest quality that still fits. The output therefore passes both checks — dimensions and file size — which is what the SSC application form actually validates. Also built in: the SSC photo preset (3.5 × 4.5 cm, 20–50 KB) for the application photograph, and a 4–12 KB preset matching older SSC notices. Like every PDFPax tool, everything runs on your device with the Canvas API: no upload, no queue, no account, no watermark. That matters for signatures — the same signature appears on your exam attendance sheet, so keeping it private is part of keeping your application safe.

The official SSC signature specification

For accuracy, here is what the official SSC/IBPS-style upload guidelines state for the signature: sign on white paper with a black ink pen (running hand only — signatures in capital letters are not accepted); dimensions 140 × 60 pixels (preferred); file size between 10 KB and 20 KB in JPG/JPEG format; and the signature must not exceed 20 KB. The same signature is used on the call letter and the attendance sheet at the examination centre — a mismatch can lead to disqualification, which is exactly why your uploaded scan should look like your real signature, just resized. Keep a copy of the resized file: if you apply for multiple SSC exams in a season, the same spec is reused across CGL, CHSL, GD, MTS and Steno forms.

Honest limits of this tool

This tool resizes and re-encodes your scan — it cannot create detail that is not there. If the original scan is very blurry, the 140 × 60 output will be blurry too; scan at 200 dpi or higher for the cleanest result. The 10 KB minimum is a real requirement, so the tool searches upward for enough quality to reach it — if even full quality cannot reach the minimum (a single very thin line), it tells you so rather than handing you a file the form would reject. The pixel dimensions are always exactly 140 × 60 (or the photo preset you chose); if a future SSC notice changes the spec, update the window using the custom min/max fields. Exam bodies occasionally revise specifications, so always confirm the current numbers on the official notification before submitting.
