Question 1

What is the official signature size for SSC CGL, GD, CHSL, and MTS?

Accepted Answer

The signature file size must strictly be between 10 KB and 20 KB in JPG/JPEG format with 300 DPI resolution. Standard dimensions are 4.0 cm width × 2.0 cm height (472 × 236 pixels) for SSC CGL/CHSL/MTS, and 6.0 cm × 2.0 cm (709 × 236 pixels) for SSC GD.

Question 2

How do I resize my signature to 10 to 20 KB without losing quality?

Accepted Answer

Upload or drag your signature photo into SSC Sign (sscsign.in). The tool automatically cleans paper shadows, whitens the background, injects 300 DPI metadata, and compresses the JPEG into the 10–20 KB range right inside your browser without any server upload.

Question 3

Why was my signature rejected on the SSC application portal?

Accepted Answer

The SSC application portal strictly checks: 1) File size is less than 10 KB or greater than 20 KB; 2) Format is not JPEG/JPG; 3) Incorrect width-to-height ratio; or 4) Blurred signature with grey shadow background.
