Why compress images to 20 KB?

Many government portals, banking portals, and university entrance exams impose a strict 20 KB limit on signature and biometric uploads to prevent database strain.

Reaching 20 KB from a high-resolution phone photo requires intelligent optimization. Our binary search engine balances quality tuning and resolution scaling so text and signatures remain sharp and legible.

Common Use Cases for 20 KB:

Signatures, thumb impressions, digital stamps, candidate avatars

Unlike traditional tools that force you to guess a quality percentage (e.g. 70%), our algorithm tests multiple quality parameters to hit under 20 KB with the highest possible visual clarity.
