SSC Signature Resizer (10KB-20KB)

SSC Signature Resizer — Resize & Compress Your Signature to 10KB-20KB Online, Free

Alongside the photograph, every SSC recruitment form — SSC CGL, SSC CHSL, SSC MTS, SSC GD Constable, Selection Post, Stenographer, JE, CPO, and the OTR profile — also asks for a scanned signature that is exactly 4 cm x 2 cm, saved as a JPG between 10 KB and 20 KB. A signature photographed on a phone is almost always the wrong shape and the wrong file size for this — the raw photo usually comes out several megabytes and shaped like whatever piece of paper it was signed on, nothing like a neat 2:1 rectangle.

This tool crops it to the exact SSC shape with a locked aspect-ratio box, then compresses it into the exact KB range in one pass, entirely inside your browser — no installation, no account, and your signature is never uploaded anywhere to do it.

SSC Signature Size Requirement: 4 x 2 cm, 400 x 200 Pixels, 10KB to 20KB

These are the figures SSC notifications have used consistently across recent recruitment cycles. SSC can revise the exact numbers from one notification to the next, so always check your own — but this is what the tool targets by default:

The signature is checked separately from the photograph, but by the same kind of automated portal validation — wrong shape, wrong file size or the wrong format all fail the exact same way, silently, before a human ever looks at it. Getting all three right at once, in one pass, is the entire point of this tool.

Which SSC Exams Need This Exact Signature Specification

Just like the photograph, the signature specification is shared across SSC's exam family — CGL, CHSL, MTS, GD Constable, CPO, JE, Selection Post and Stenographer — because they all draw on the same OTR profile. Sign once, in the correct shape and size, and that signature generally carries forward to every SSC application you make afterwards, the same way the photograph does. It is worth taking the extra minute to get a genuinely clean, confident signature the first time, rather than re-scanning a rushed one for every exam form separately.

How to Resize Your SSC Signature Online — Step by Step

1. Sign on plain white, unruled paper with a black or dark blue ballpoint or gel pen — your normal running signature, the way you would sign a bank cheque, never in separated block capital letters.
2. Photograph or scan just the signature in good, even daylight — no harsh shadow falling across the ink — and upload it here.
3. Drag the crop box tightly around the signature strokes, with a small margin of white paper around them. The box is locked to SSC's 4x2 cm (2:1) shape, so it cannot come out the wrong proportions.
4. Pick a target size between 10 KB and 20 KB — 15 KB is a safe middle choice most SSC and OTR forms accept.
5. Press "Crop & compress", confirm "Within target" shows a green tick, then download the JPG and upload it to your SSC application.

Common SSC Signature Upload Errors — and How This Tool Avoids Them

• "File size does not match" / "Invalid image size" — the scan was above 20 KB or below 10 KB. Picking a chip on this page (12/15/18/20 KB) fixes this on its own.
• "Dimensions do not match specified aspect ratio" — the crop was not a true 4x2 cm (2:1) shape. The crop box here is locked to that ratio, so it physically cannot come out the wrong shape.
• "Invalid file format" — a PNG or WEBP photo of the signature was uploaded where only JPG is accepted. This tool always outputs JPG regardless of what you upload.
• Signature rejected as "typed" or "block letters" — SSC wants a hand-signed, running/cursive signature. Sign normally, the way you sign a bank cheque, not in separated capital letters.
• Signature looks faint or grey after compression — sign with a black or dark blue ballpoint/gel pen for strong contrast; a light gel pen or pencil fades badly at low file sizes.

Tips for a Signature Scan That Compresses Cleanly

• Sign fairly large on the paper first, then crop down — a signature that was originally tiny loses detail badly once it is stretched up to fill the 4x2 cm box.
• Use a fresh ballpoint or gel pen; a dried-out pen leaves faint, broken strokes that compress into an illegible smudge at 10-20 KB.
• Photograph it flat, directly from above, not at an angle — an angled shot distorts the proportions before you even get to cropping.
• Avoid glossy or textured paper; plain matte white paper gives the cleanest contrast between the ink and the background.
• Keep the same signature you use on your Aadhaar, bank documents and other official paperwork — consistency matters more than how elaborate it looks.

Why This SSC Signature Resizer Is Safe to Use

A signature is used to verify identity, so it deserves the same caution as any other ID document. This tool never uploads your signature anywhere: the crop and the compression both run as JavaScript inside your own browser tab, using the HTML5 Canvas every modern browser already ships with — not a plugin, not a server-side script. There is no "upload" step to watch for; the finished file only leaves your device once, the moment you press Download, and it goes straight into your own downloads folder. The moment you close the tab, nothing of your signature remains anywhere but your own device — no account needed, no server-side copy left behind to worry about.

SSC Signature Resizer vs. Resizing by Hand in Paint or Photoshop

Getting a phone photo of a signature down to a precise 4x2 cm shape and 10-20 KB by hand in Paint means converting centimetres to pixels yourself, guessing at a "Save As" quality level, and checking the resulting file size over and over. This tool's crop box is pre-locked to the exact SSC shape, and the compression step automatically searches for the JPEG quality that lands inside your chosen KB target — no trial and error, and no risk of the wrong aspect ratio slipping through.
