Exact SSC photo and signature specs (CGL, CHSL, MTS) with free resizing tools that never upload your files.
| File | Format | Size | Dimensions | Notes |
|---|---|---|---|---|
| Photograph (CHSL/MTS upload) | JPG / JPEG | 20 KB – 50 KB | 3.5 × 4.5 cm | Light background, no cap/glasses, recent |
| Signature | JPG / JPEG | 10 KB – 20 KB | 140 × 60 px (~4×2 cm) | Black ink on white paper, not capitals |
Specs can change between notifications — always confirm against the official SSC information bulletin / upload page.
Note: SSC CGL now captures the photo live during the application (no upload), but CHSL, MTS, GD and other SSC exams still require an uploaded photo at 20–50KB. Always check your exam's upload page.
Your SSC photo and signature are identity documents. Unlike most resizer sites, Convert.AI processes everything in your browser — your files never touch a server. Free, unlimited, no watermark, no signup.

Use our compress tool to bring it to the required KB range without losing clarity. It runs in your browser, so your photo is never uploaded.
Some portals reject files below the minimum size. Use the Increase Image Size tool to pad it up to the required KB.
Yes — everything happens in your browser. Your photo and signature never leave your device, which matters for an identity document.
