Image Compression Guide

What is Target KB Compression?

Target KB compression reduces the file size of a photo (such as from 3MB down to 20KB) by adjusting JPEG DCT quantization tables, canvas pixel dimensions, and color space bitrate inside web browser memory buffer (RAM).

How Binary Search Quality Iteration Works

Govt Photo Resizer evaluates canvas rendering streams using an iterative binary search algorithm (5 to 8 iterations). It calculates the highest possible quality level (e.g. 84% quality at 48.2 KB) that strictly remains beneath your specified target (e.g. 50 KB).
