When to Convert to WebP
WebP is the recommended format for all web images today. Converting JPG and PNG images to WebP before uploading to your website significantly reduces page load time. Google's PageSpeed Insights and Core Web Vitals both reward WebP usage. All modern browsers including Safari (since version 14) support WebP fully.
