Understanding the 20 KB Target Requirement
Why online forms and submission portals require this specific size
Many government recruitment portals (such as SSC, UPSC, and state PSCs), banking KYC systems, and university entrance forms require candidate signature and photo uploads to meet a specific file size bracket—often between 10 KB to 20 KB (or a 20 kb photo size / jpg 20 kb minimum). If your scanned signature or cropped JPG image is under 20 KB or was compressed too aggressively by phone cameras, SizeIncreaser safely increases the file weight to help satisfy 20 KB upload criteria.

Is it safe to upload sensitive documents like signature scans here?
