What it does and why it matters
Large images are the most common reason websites load slowly, which hurts both user experience and Google's Core Web Vitals. WebP typically delivers noticeably smaller files than JPG or PNG at similar visual quality.
This tool resizes and re-encodes your image to WebP directly in your browser. Nothing is uploaded, so it is safe for private photos and client work.
