About This Tool
WebP is an image format developed by Google that is often 20–30%+ smaller than JPEG/PNG, which helps page speed and Core Web Vitals. This tool runs libwebp compiled to WebAssembly inside your browser, so your images are never uploaded to any server — safe even for logos and unreleased designs.
