How Image Compression Works
JPEG and WebP use lossy compression, meaning image quality can be traded for file size. This tool binary-searches the compression quality (1-100%) so the resulting file lands as close as possible to your target size, without going over it, while keeping quality as high as possible.
This is especially useful for meeting upload limits — government forms, job portals, and many websites cap uploads at a specific KB size like 50KB, 100KB, or 200KB.
