About This Conversion
WebP is a modern image format developed by Google that provides superior compression compared to both PNG and JPG. Converting PNG to WebP typically reduces file size by 25-35% for lossless content and up to 80% with lossy compression — while maintaining transparency support. This makes WebP ideal for web performance optimization. All modern browsers (Chrome, Firefox, Safari, Edge) support WebP. This conversion is particularly valuable for websites where every kilobyte of image data affects page load speed and Core Web Vitals scores.
