WebP Guide: Why & How to Optimize Your Images

Why loading speed matters

In modern web design, loading speed has become the key factor for a website's success. A page that takes more than three seconds to display loses, on average, more than half of its visitors. To address this performance issue, Google developed the WebP format — a revolutionary image compression technology designed specifically for the web.

The major SEO benefits of WebP

• Drastic file size reduction: on average, an image converted to WebP is 25 % to 34 % lighter than an equivalent JPEG, and up to 80 % lighter than a PNG file, while keeping identical visual quality.
• Improved Core Web Vitals: the weight of your graphic files directly influences Google's LCP (Largest Contentful Paint) metric. Optimizing your visuals lets you turn green on Google PageSpeed Insights.
• Better mobile UX: on smartphones, where connections can be unstable, light images guarantee fluid navigation and reduce your users' data consumption.
