Why Government Portals Limit PDF File Sizes
Government and banking recruitment portals (such as IBPS, UPSC, and RRB) mandate that supporting documents like 10th/12th marksheets, caste certificates, and graduation degrees must be uploaded under tight limits, typically 100 KB, 200 KB, or 300 KB.
High-resolution smartphone scans often produce multi-megabyte PDF files that overload portal upload queues and get automatically rejected.
Balancing Resolution and Readability
When compressing PDFs, the primary challenge is ensuring that serial numbers, roll numbers, board seals, and authority signatures remain perfectly legible. Over-compressing can convert text into unreadable pixelated artifacts.
Using client-side vector-preserving PDF compression streams ensures that text sharpness is maintained while stripping redundant background metadata.
