When opening bank accounts or verifying Demat/Mutual Fund KYC online, scanned black-and-white signature crops or PDF certificates often measure merely 4 KB to 15 KB.

However, bank security forms frequently require uploads between 50 KB and 500 KB (or minimum 100 KB for PDFs). SizeIncreaser allows you to increase signature files and PDF certificates up to your target size in a fraction of a second with zero privacy risk.
