How GS DocSeva Resizes Images to Exact File Sizes
Online government job applications, university registrations, and visa document portals enforce rigorous file limits—demanding images between 20 KB to 50 KB, or exactly under 100 KB.
GS DocSeva utilizes an intelligent client-side binary search routine combined with progressive step-down canvas downscaling. Instead of arbitrary pixel crushing, our local canvas engine iteratively converges on the highest possible JPEG quantization matrix that satisfies your ceiling limit while maintaining maximum facial contrast and clean text clarity.
