Why image compression matters for web performance
Images account for nearly 50% of average page weight. Unoptimized images are the single biggest reason websites fail Google's Core Web Vitals, directly hurting your Largest Contentful Paint (LCP) score. Every 100ms of additional load time can reduce conversions by up to 7%. Compressing images is the fastest way to improve both rankings and user experience.
This tool uses MozJPEG, WebP and OxiPNG compression that runs entirely in your browser via WebAssembly. Your files never leave your device, making it perfect for sensitive or proprietary images. WebP format typically delivers 25-35% smaller files than JPEG at equivalent quality, which is why we recommend it as the default output format.
