Why Target 300KB for Application Documents?
Examination commissions like the Union Public Service Commission (UPSC) and national recruitment boards set a strict 300 KB file limit for identity proofs, caste certificates, and academic qualifications. Uploading a file of 301 KB triggers an immediate rejection. SizeSnap automatically targets ~285KB to 295KB, giving you an exact safety buffer.
