Signature Resize 10 KB to 20 KB in JPG (SSC, IBPS, SBI & UPSC)

A massive volume of exam applicants face upload rejection because their signature file exceeds 20 KB or fails the 10 KB minimum file size rule. Major recruitment boards across India—such as SSC (Staff Selection Commission), IBPS, State Bank of India (SBI), Railway Recruitment Boards (RRB), and UPSC—mandate signatures strictly within the 10 KB to 20 KB bracket in JPG/JPEG format.

Use the official exam specifications table below to configure your signature and photo dimensions correctly before submitting:

Exam / Organization	Required File Size	Dimensions (cm & px)	Format
SSC CGL / CHSL / MTS Signature	10 KB to 20 KB	4.0 cm × 2.0 cm (140 × 60 px)	JPG / JPEG
IBPS PO / Clerk / SBI Signature	10 KB to 20 KB	140 × 60 px	JPG
Left Thumb Impression (IBPS/SBI)	10 KB to 20 KB (or 20–50 KB)	3.0 cm × 3.0 cm (240 × 240 px)	JPG
Passport Photograph (SSC/Bank)	20 KB to 50 KB	3.5 cm × 4.5 cm (200 × 230 px)	JPG

Important Guidelines for Signature Uploads

Ensure the signature is on plain white paper without lines or grids.
Use dark black or blue ink pen for maximum contrast.
Crop closely around the signature to prevent large white borders from bloating file size.
Do not upload in CAPITAL letters if the portal disallows block letter signatures.
