How Client-Side Image Binary Compression Works Under the Hood
When you select a target size (e.g., 20KB or 50KB), ResizeInKB executes an in-browser binary search algorithm using the HTML5 HTMLCanvasElement.toBlob() API. It dynamically adjusts JPEG quantization matrices and pixel dimensions directly inside your browser's V8 JavaScript engine memory. Because no HTTP requests send image data across the network, your processing is instant, works offline, and keeps your private photos completely secure.
