# Why Online Portals Require Strict PDF Size Limits

Online government recruitment portals (UPSC, SSC, State PSC, IBPS, Railways) and university admission systems handle millions of file uploads simultaneously. To prevent database congestion and server crashes, application forms enforce rigid **maximum file size limits** (e.g. *"Upload Marksheet PDF between 50 KB and 200 KB"*).

Attempting to upload a standard 1.5 MB scanned certificate will trigger rejection errors like *"File size exceeds 200 KB limit"*.
