When applying for Indian government exams, you will notice highly specific requirements for digital signature uploads. While photographs are typically allowed 20KB to 50KB, signatures are almost universally restricted to the 10KB to 20KB range.

This strict limit exists because signatures don't require high-resolution color depth. Large signature files unnecessarily bloat backend institution servers without providing any functional benefit for identity verification. By forcing a 10-20KB limit, institutions like the Staff Selection Commission (SSC) and the Railway Recruitment Board ensure millions of applications can be processed and stored efficiently.
