What Is the WebP Image Format?
WebP is a modern image format created by Google that provides better compression than JPEG or PNG — resulting in faster-loading websites and smaller file sizes without sacrificing image quality. It supports both lossy and lossless compression, plus alpha transparency for clear backgrounds and overlays.
WebP is now supported across all major browsers and platforms, making it the ideal format for developers, designers, and everyday users who want lightweight, high-quality images. Whether you're converting for SEO, reducing page speed metrics, or building apps, using WebP helps deliver better performance and user experience.
